The Lahore Session of Congress took place in 1929, since it adopted Purna Swaraj as the national goal. On the Lahore Session of Congress: jawaharlal Nehru hoisted the tricolour on the banks of the river Ravi at midnight, and 26 January was fixed as the day on which Congress workers across the country would take the independence pledge every year. The Lahore Session of Congress belongs to the 1927-1947 phase of India's national movement, and exam setters often pair the Lahore Session of Congress with neighbouring milestones on this timeline to test precise, date-wise recall. 1940 is incorrect because the Lahore Session of Congress is dated to 1929, not 1940. 1945 is incorrect because the Lahore Session of Congress is dated to 1929, not 1945. 1935 is incorrect because the Lahore Session of Congress is dated to 1929, not 1935. Competitive exams such as SSC CGL, SSC CHSL, State PSC, and Railway exams frequently test the Lahore Session of Congress of 1929, 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 Lahore Session of Congress 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: Lahore Session of Congress — 1929 — Jawaharlal Nehru.
