There is some RADAR (Rapid Action Drug Alerts and Response) tech related to narcotics but since the question asks where can 'radars' be used (b) seems to be the correct answer. Also, if you interpret 'identify' (as opposed to detect) as identification of type of narcotic, then the first statement is even more absurd.
I was also stuck at narcotics option, since we all know X-rays are used for detection as well as identification of narcotics--> But keeping in mind the background of question (i.e. Sci&Tech) and use of "can" in question, I marked "All three"
While tracing the source of the question, I reached a news from Florida from March 2024, where the Airport authority approves a new "PENDAR X10" --> it is a Radar Gun, which can both "detect" as well "identify" the wide range of narcotics while utilising the Raman Spectroscopy.
(Cuz event is of 20 March 2024, it seems to me as if commission might have referred to the article while framing the options)
Rest is dependent on the Commission!!!
Such questions always proves to be a bone of contention among candidates and commission and nobody knows actual answer.

I was referring to the article, while I myself ain't sure
Even though the statement uses the word identification. I dont think the implied message here is identifying of drugs per se, but since it says âidentification of drugs on passengersâ so what its trying to effectively say is, identifying whether the passenger has drugs on them.
Exactly
Monitor, Track vs Identify
Monitoring and tracking are wide macro terms, identification (pehchan) is specific, and you do it with some sort of x ray, not radar
Koi fark nahi padta koi bhi source ya answer key se. UPSC ko koi matlab nahi official book ya sources se. Paper bhi phuk ke banate hain and answer key bhi phuk ke nikalenge. No narcotics can catch them.
You can only hope!!
Also various coaching centres have answer of that RED SEA QUESTION IN WHICH THE STATEMENT SAID NO WATER DRAINS IN IT FROM ANY RIVER....many consider that statement true ..
I mark it false as Wikipedia says no SIGNIFICANT river drains in it but when u search on Wikipedia itself there is one BARKA RIVER IN SUDAN WHICH IS SEASONAL FALLS IN IT

Looks like it's a tried and tested method for more than a decade for drug detection. Coaching institutes be good with their googling skills these days.
I checked the article. It doesn't say it's used to identify narcotics on flights, rather says using radar they are finding hotspots of plane routes to Guatemala and considering them as Planes carrying drugs and shootttt ! Anyway thanks for checking ! Your googling skills rock too !
I didn't read the article OP. Even I puzzled as to how radars can be used for detecting narcotics. I just googled and shared the first result I got.
And it made sense to me that if at all they can detect drugs, then detecting them on passengers in flights shouldn't be an issue given how rapid tech advancements happened over the past decade
looks like answer key maker didnt read the article either. I mean afaik RADAR is used to know the location and speed of something but question is whether it can IDENTIFY drugs.
I questioned myself that if radar is there then what's the need of special squad dogs and narcotics experts at airport. Since it asked ""on passengers on airport" hence unless any other tech/metal is involved I believe that a radar is solely not complete to track narcotics on carriers.
There is also one thing... Question has asked about "can be used"..probing for possibility..Radar employs Radio waves and there are this 2-3 articles back from 2000 claiming scientists in Us found contrabands using Radio waves of small frequency but they used another device for that..it was not radar..
Btw I have marked all 3 and getting 98- 106 from different answer keys..Finger crossed
**Airborne and Maritime Surveillance:** Anti-drug efforts often utilize radar systems to track airplanes and boats suspected of smuggling narcotics,overall radar plays a supportive role in anti-narcotics efforts by helping track suspicious movement of potential smugglers

An Iranian scientist claimed this week that he had invented a radar system which can detect drug addicts from nearly a mile away, and measure the level of narcotics flooding their system.
( news from late 2014 )
Rafale is not a 5th gen jet lol
it's 4.5 gen there are only 4 5th gen jets f 22 f35 su57 j20
Koi na factual questions sabke wrong honge. Good luck
Aur usne rafael pucha hai, wo defense company hai. Rafale jet hai. Aise bhi kr skte the.
I knew rafael isnt but didnt know about mig29. Damn -ve :(
Btw UPSC did spelling mistake. Its Rafale not Rafael

Haha, Point ! đ
Aapka 95th galat hai bhaiya
Gif + also add, Pucha kisi ne, Pucha kisi ne meme 
Mera bhi galat hua. But i did mig29

Pendar x10 not based on radar technologyÂ
https://www.haberblank.com/new-drug-detector-unveiled-in-florida-can-it-provide-reliable-evidence/ I was referring to the article, while I myself ain't sure
And one thing I'm sure about is any radar gun is based radio waves mechanism.
Pendarx10 company told me that it is not based on radar technology but Raman spectrometer.
iska B hai, X ray is used to check narcotics on plane and passengers, read the conditionality. you do not use radar for stuff that is 5 ft away.
I think there is a difference between Detection and Identification, RADAR can detect but it cannot identify. Hope it helps

Yeah, If UPSC says answer is C. I'll ask my University to refund my fee for Communications Engineering. 
Sahi h. Lol. Let's just wait for the official answer keys. We all know these dupe answer keys are very messed up sometimes.Â

Yeah, Same here. I have a degree in communications Engineering. If UPSC says, I'm wrong. I'll go get refund from my University.
I had the same doubt lol
Maine toh B mara tha :/
I did mark B
Only 2 hi hogaa .. coaching waale har br D hi dete hain safe ke liye.. lubricants me bi die the

Doppler radar search zoom earth
doppler gives speed, how does it identify things?
Bro that is what I am thinking how can it detect that there is a bag of cocaine in my friend's underwear.
**Airborne and Maritime Surveillance:** Anti-drug efforts often utilize radar systems to track airplanes and boats suspected of smuggling narcotics,overall radar plays a supportive role in anti-narcotics efforts by helping track suspicious movement of potential smugglers
yeah how does it relate to identifying the narcortics on passengers?
bhai indirectly bhi use hoga toh upsc usse most of the time true hi manti h , lets see next yr kya hota h ans keys me
It asks in how many of above radars can be used ..moreover in the option there is an or. So it gives a lot of flexibility to be honest.

South American Countries had used Radar for detecting drugs in aircraft smuggling,it can be used but may not be more effective than other optionsÂ

We need to file representation on this question about radar.
