Correct Answer:
B. 23rd March 1956
Explanation:
The correct answer is 23rd March 1956 because this marks the exact date when Pakistan's first formal, home-grown constitution came into full operational effect.
- Step 1 (Constituent Progress): Following independence, Pakistan operated under an adapted Government of India Act 1935 until the Constituent Assembly completed and passed this framework.
- Step 2 (State Transition): The enforcement of the 1956 constitution officially changed the Dominion of Pakistan into the Islamic Republic of Pakistan, introducing a parliamentary setup.
- Incorrect Options:
- 14th August 1947 is incorrect because this is Pakistan's Independence Day, when it began running on transitional colonial frameworks rather than its own constitution.
- 14th August 1973 is incorrect because this is the date the current, third permanent constitution of Pakistan was enforced.
- 27th October 1958 is incorrect because this marks the country's first successful military coup d'état led by General Ayub Khan, which had already abrogated the 1956 constitution.
