When was the 1956 Constitution of Pakistan enforced?

Pakistan's first constitution was actually promulgated on 23 March 1956, not 1952. Assuming the question refers to the enforcement date of Pakistan's first constitution, 23 March is the correct day. This date is highly significant in Pakistan's history, as it is celebrated as Pakistan Day, commemorating the Lahore Resolution of 1940 and the adoption of the first constitution. Option A (14 August) is Pakistan's Independence Day. Option B (8 June) is not associated with the enforcement of Pakistan's constitution. Therefore, 23 March is the accurate date for the enforcement of the first constitution.
