- Statement 1: For an ordinary bill to become an Act, it must be passed by both Houses of Parliament (Lok Sabha and Rajya Sabha), either identically or with amendments agreed upon by both Houses (or through a joint sitting in case of deadlock, though this doesn't apply to Money Bills). This statement is correct. - Statement 2: After a bill has been passed by both Houses, it is presented to the President for assent. Article 111 states that when a bill is presented to the President, he shall declare either that he assents to the bill, or that he withholds assent, or in the case of a non-money bill, he may return it for reconsideration. Assent by the President is mandatory for the bill to become law. This statement is correct. - Statement 3: The Prime Minister's signature is not a step required for a bill passed by Parliament to become an Act. The President gives assent. This statement is incorrect. - Statement 4: The Supreme Court's role is judicial review, which happens after a law has been enacted. It does not approve a bill or declare its jurisdiction during the legislative process. This statement is incorrect.
