Exp) Option c is the correct answer.

The Parliament occupies a central position and has a multifunctional role. It has legislative, executive, financial, constitutional, judicial, electoral powers and functions associated with it.

Statement 1 is correct: Parliament exercises control over the Executive through question-hour, zero hour, half-an-hour discussion, short duration discussion, calling attention motion, adjournment motion, no-confidence motion, censure motion and other discussions.

Statement 2 is incorrect: The primary function of Parliament is to make laws but the implementation of laws is totally the role of the executive.

Statement 3 is incorrect: Neither the executive nor the Parliament has the power to be the final interpreter and protector of the constitution, the power lies in the hand of the Supreme Court.

Statement 4 is correct: Parliament is vested with the powers to amend the Constitution by way of addition, variation, or repeal of any provision without changing the basic structure of the Constitution.

Statement 5 is correct: According to the Constitution, no tax can be levied or collected and no expenditure can be incurred by the Executive except under the authority and with the approval of Parliament. Hence, the budget (Annual Financial Statement) is placed before the Parliament for its approval. The enactment of the budget by the Parliament legalises the receipts and expenditure of the government for the ensuing financial year.
