RAS question
DRDO's Comprehensive Test Ban Treaty Organisation (CTBTO) monitoring station in India is at:
Correct answer: (B) There is no CTBTO station as India hasn't signed CTBT.
India has no CTBTO monitoring station, because it has not signed the Comprehensive Nuclear-Test-Ban Treaty.
Explanation
The premise of a DRDO CTBTO monitoring station in India is wrong. CTBTO describes the CTBT as a treaty banning nuclear weapon test explosions everywhere and says its verification regime is built around the International Monitoring System, the International Data Centre and on-site inspections after entry into force. The same CTBTO account lists India among the Annex 2 states that are yet to sign the Treaty. India has stayed outside the CTBT, regards it as discriminatory because it does not address vertical proliferation by recognised nuclear states, and still maintains a voluntary moratorium on nuclear testing. No Indian city or test site hosts a CTBTO monitoring station.
Why the other options are wrong
- (A) Delhi is not a CTBTO monitoring-station site; the issue is India's CTBT status and the absence of any such station in India.
- (C) Pokhran is a tempting nuclear-test association, but India has no CTBTO monitoring station.
- (D) Mumbai does not fit the official CTBTO position either, because the correct fact is that no CTBTO monitoring station exists in India.
Concept
India's nuclear-policy position on the CTBT and the CTBTO verification regime is a recurring RAS theme because treaty questions often turn on India's formal position, not on familiar nuclear locations.
