Exp) Option d is the correct answer

The office of whip serves as an assistant floor leader of the political party. Every political party, whether ruling or Opposition has its own whip in the Parliament. He is appointed by the political party. He regulates and monitors their behaviour of the members of the political party in the Parliament. He ensures the attendance of his party members in large numbers. He secures their support in favour of or against a particular issue. The members are supposed to follow the directives given by the whip. Otherwise, disciplinary action can be taken. The office of ‘whip’ is based on the conventions of the parliamentary government. It is mentioned neither in the Constitution of India nor in the Rules of the House nor in a Parliamentary Statute.
