The correct answer is option 3, the President of India. The appointment of Judges of the Supreme Court of India is done by the President of India. The President has the power to appoint Judges in consultation with other high-ranking officials.

Option 1, the Supreme Court Collegium, is incorrect. While the Supreme Court Collegium does play a role in the process of appointing Judges, they recommend names to the President for consideration. The final appointment is made by the President.

Option 2, the Cabinet, is also incorrect. The Cabinet is a body of ministers that advises the President, but they do not have the authority to directly appoint Supreme Court Judges.

Option 4, the Lok Sabha, is also incorrect. The Lok Sabha, which is the lower house of the Indian Parliament, is not involved in the appointment of Supreme Court Judges. This power lies with the President of India.

It is important to note that the President appoints Judges based on the advice and recommendations of various authorities, including the Chief Justice of India, other Judges of the Supreme Court, and the Governor of the state where the appointment is taking place.
