Who among the following leaders did NOT participated in the Second Round Table Conference?

The answer is D) Dr. Rajendra Prasad. He was not among the Indian National Congress delegates to the Second Round Table Conference (London, September to December 1931), so he did not take part.

• A) M.K. Gandhi: Wrong. Gandhi attended as the sole Congress representative after the Gandhi-Irwin Pact of March 1931 ended the Civil Disobedience Movement.
• B) Sarojini Naidu: Wrong. She was one of the Congress delegates at the conference.
• C) Pt. Madan Mohan Malaviya: Wrong. He was also a Congress delegate to the Second Round Table Conference.

The core concept is the sequence of the three Round Table Conferences. Congress boycotted the first (1930) and the third (1932), and took part only in the second, after the Gandhi-Irwin Pact. For Mains, this links to the constitutional reform process that led to the Government of India Act, 1935.

Trap: Aspirants often assume that every prominent Congress leader of the period was at the London conference. Check the delegate list rather than relying on who was prominent in the movement.
