- Statement (A): India's nuclear program began in the 1940s, but it became more prominent in 1974 after the first nuclear test (Smiling Buddha). Homi J. Bhabha played a major role in its development, but it was not started in 1952.
- Statement (B): India has historically been against the Non-Proliferation Treaty (NPT), as it discriminates between nuclear-armed states and non-nuclear states.
- Statement (C): India has recently made it clear that the policy of 'no first use' of nuclear weapons could be reviewed, depending on the changing security environment.
- Statement (D): Nehru, the first Prime Minister of India, was not against nuclear weapons but strongly advocated for disarmament.
Thus, the correct answer is (C) Now India has made it clear that the policy of 'no first use' can be reviewed.
