Article 79 of the Indian Constitution defines Parliament as consisting of the President, the Rajya Sabha, and the Lok Sabha. While the President is not a member of either House, they are an integral constituent of Parliament. The President summons and prorogues sessions, can address both Houses, and must give assent to bills before they become law. Options C and D incorrectly include the Cabinet or Council of Ministers, which are part of the executive, not legislature.
