Who advises the President on matters of national importance?

In Pakistan's parliamentary system, the President serves as the ceremonial Head of State, while the executive authority primarily rests with the Prime Minister and the Cabinet. The Constitution outlines the advisory role for the President. The correct answer is C: PM & Cabinet. Article 48 of the Constitution explicitly states that the President shall act in accordance with the advice of the Cabinet or the Prime Minister. This ensures that major decisions on matters of national importance are a collective responsibility of the executive branch. Distractor A, PM, is partially correct as the Prime Minister is the chief executive, but the Cabinet also plays a crucial advisory role. Distractor B, Cabinet, is also partially correct, but the Prime Minister leads the Cabinet and is central to policy formulation. Therefore, the combined advice of both is the most accurate representation of the constitutional provision. Distractor D is incorrect as specific advisory mechanisms exist.
