Who was most closely associated with the Independence Day pledge?

Indian National Congress was most closely associated with the Independence Day pledge (1930), since 26 January was observed as Independence Day after the Purna Swaraj resolution. On the Independence Day pledge: the pledge was read out at public meetings across India and became the first organised, nationwide observance of an Independence Day, years before actual independence arrived in August 1947. The Independence Day pledge belongs to the 1927-1947 phase of India's national movement, and exam setters often pair the Independence Day pledge with neighbouring milestones on this timeline to test precise, date-wise recall. Sardar Vallabhbhai Patel is incorrect here because Sardar Vallabhbhai Patel is linked with the Karachi Session of Congress (1931), not the Independence Day pledge. Subhas Chandra Bose is incorrect here because Subhas Chandra Bose is linked with a different milestone of this period, not directly with the Independence Day pledge. Sir Stafford Cripps is incorrect here because Sir Stafford Cripps is linked with the Cripps Mission (1942), not the Independence Day pledge. Competitive exams such as SSC CGL, SSC CHSL, State PSC, and Railway exams frequently test the Independence Day pledge of 1930, 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 Independence Day pledge 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: Independence Day pledge — 1930 — Indian National Congress.
