Identify the event linked with Lord Mountbatten in 1947.

The Mountbatten Plan (1947) is the event linked with Lord Mountbatten in 1947, since it accepted partition and provided the immediate framework for transfer of power. On the Mountbatten Plan: it set 15 August 1947 as the date for the transfer of power, and it led directly to the Indian Independence Act, 1947, passed by the British Parliament. The Mountbatten Plan belongs to the 1927-1947 phase of India's national movement, and exam setters often pair the Mountbatten Plan with neighbouring milestones on this timeline to test precise, date-wise recall. Lahore Session of Congress is incorrect because the Lahore Session of Congress took place in 1929, not 1947, so it does not fit this question on the Mountbatten Plan. Gandhi-Irwin Pact is incorrect because the Gandhi-Irwin Pact took place in 1931, not 1947, so it does not fit this question on the Mountbatten Plan. Government of India Act is incorrect because the Government of India Act took place in 1935, not 1947, so it does not fit this question on the Mountbatten Plan. Competitive exams such as SSC CGL, SSC CHSL, State PSC, and Railway exams frequently test the Mountbatten Plan of 1947, 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 Mountbatten Plan 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: Mountbatten Plan — 1947 — Lord Mountbatten.
