The correct answer is option 3: The Supreme Court. The Indian Judiciary is the system of courts that interprets and applies the law in India. It is headed by the Supreme Court, which is the highest judicial authority in the country. The Supreme Court consists of a Chief Justice and other judges appointed by the President. It has the power of judicial review and can declare laws or executive actions unconstitutional. The President, option 1, is the head of state in India and does not directly oversee the judiciary. The Prime Minister, option 2, is the head of government and is also not directly involved in the functioning of the judiciary. The Parliament, option 4, is the legislative body responsible for making laws, but it does not head the judiciary.
