Correct Answer:
B. The Speaker's decision is final.
The Constitution of Pakistan grants significant authority to the Speaker of the National Assembly regarding Money Bills. The Speaker's decision on whether a Bill is a Money Bill or not is final.
Option A is false because the Speaker's decision is binding and cannot be overridden by the President or any other authority, ensuring clarity and preventing disputes.
Option C is false as the Speaker's determination is an independent constitutional function, not subject to approval by the Federal Government.
Option D is false because the Speaker plays a crucial and definitive role in certifying Money Bills, which is essential for parliamentary procedure and financial governance.
