The correct answer is (c), Article 123.
Article 123 of the Indian Constitution vests in the President of India the power to promulgate ordinances when Parliament is not in session. Ordinances have the same force and effect as an Act of Parliament, but they must be laid before Parliament as soon as it reassembles and cease to have effect on the expiry of six weeks from the reassembly of Parliament, or earlier if they are withdrawn by the President or disapproved by Parliament.
Article 74 deals with the appointment of the Prime Minister and other Ministers of the Union. Article 78 deals with the President’s power to make rules for the more convenient transaction of the business of the Government of India. Article 124(2) deals with the qualifications for appointment as the Chief Justice of India.
