When was the Constitution of Pakistan 1973 enforced?

The Constitution of Pakistan 1973 is the supreme law of the land, providing the framework for the government and defining fundamental rights. It was adopted by the National Assembly on April 10, 1973, but its enforcement was strategically set for a date of national significance. The correct answer is A: 14th Aug 1973. This date marks Pakistan's Independence Day, making the enforcement of the new constitution a symbolic gesture of national sovereignty and the establishment of a fully functional constitutional government. Distractor B, 15th July 1973, holds no constitutional relevance. Distractor C, 23rd March 1973, is Pakistan Day, commemorating the Lahore Resolution and the adoption of the 1956 Constitution, but not the enforcement of the 1973 Constitution. Distractor D, 27th Oct 1, is an incomplete and incorrect date.
