Explanation
Mahatma Gandhi and B R Ambedkar was most closely associated with the Poona Pact (1932), since it replaced separate electorates for the Depressed Classes with reserved seats in joint electorates. On the Poona Pact: it was signed after Gandhi undertook a fast in Yerwada Jail against the Communal Award's separate electorates for the Depressed Classes, and the pact's joint-electorate compromise ended his fast. The Poona Pact belongs to the 1927-1947 phase of India's national movement, and exam setters often pair the Poona Pact with neighbouring milestones on this timeline to test precise, date-wise recall. Lord Linlithgow is incorrect here because Lord Linlithgow is linked with the August Offer (1940), not the Poona Pact. Lord Wavell is incorrect here because Lord Wavell is linked with the Wavell Plan (1945), not the Poona Pact. Lord Mountbatten is incorrect here because Lord Mountbatten is linked with the Mountbatten Plan (1947), not the Poona Pact. Competitive exams such as SSC CGL, SSC CHSL, State PSC, and Railway exams frequently test the Poona Pact of 1932, so keeping the year, the key person, and the outcome linked together in memory helps avoid confusion with nearby events in the national movement timeline. Candidates preparing for the Poona Pact question should also revise the events immediately before and after it on the 1927-1947 timeline, since paper-setters frequently frame options using adjacent years and closely related personalities. Remember: Poona Pact — 1932 — Mahatma Gandhi and B R Ambedkar.
