In which of the following Sessions of Indian National Congress, Mahatma Gandhi said, “Gandhi may die but Gandhism will remain forever”?

The answer is D, Karachi Session, 1931. This was the March 1931 session presided over by Sardar Vallabhbhai Patel, held soon after the Gandhi-Irwin Pact. Gandhi attended and addressed it, and the session is linked with the Fundamental Rights and Economic Programme resolution. The quoted remark is widely cited in connection with this session, though the exact wording varies across sources, so check the primary report if you are asked to quote it.

• A (Calcutta, 1928): Motilal Nehru presided. The session endorsed the Nehru Report and set a one-year deadline for dominion status.
• B (Lahore, 1929): Jawaharlal Nehru presided. The session adopted the Purna Swaraj resolution on 31 December 1929.
• C (Madras, 1927): Dr M.A. Ansari presided. The session decided to boycott the Simon Commission and moved towards the demand for complete independence.

The core concept here is the Congress's shift from dominion status to Purna Swaraj, and the Karachi session's economic resolution, which is a useful Mains link to the socio-economic thought of the freedom movement.

Trap: Candidates often pick Lahore 1929 because it is the famous Purna Swaraj session. Remember that the Gandhi quote is linked to Karachi 1931, not Lahore.
