The primary condition for a bill to be considered a Money Bill in Pakistan is its origin. According to the Constitution, it must originate in the National Assembly. This reflects the National Assembly's central role in controlling public finance.
Option A is false because while the Senate reviews bills, Money Bills cannot be passed by the Senate in the same manner as ordinary legislation; its role is advisory and limited to recommendations.
Option C is false because presidential approval is the final step for any bill to become law, not a condition for its classification as a Money Bill.
Option D is false because while a Money Bill is indeed related to the financial obligations of the Federal Government, this describes its subject matter, not the procedural condition for its classification.
