When was the 18th Amendment Bill passed by the National Assembly?

Correct Answer: April 15, 2010

The 18th Constitutional Amendment Bill was passed unanimously by the National Assembly of Pakistan on 15 April 2010. It is regarded as one of the most significant constitutional reforms in Pakistan's history, restoring parliamentary democracy, enhancing provincial autonomy, and repealing many provisions introduced under military rule.

Why the other options are incorrect:

• March 12, 2010: The Bill had not yet been passed by the National Assembly on this date.
• May 12, 2010: By this date, the Bill had already been approved by Parliament and was moving through the final constitutional process.
• June 08, 2012: This date is unrelated to the passage of the 18th Amendment Bill.
