The correct answer is option 1, the President. The President holds the power to appoint judges of the Indian Supreme Court. This is in accordance with Article 124 of the Indian Constitution, which states that the President shall appoint judges in consultation with other relevant authorities such as the Chief Justice and other Supreme Court judges. It is important to note that while the President has the power to appoint judges, the appointment must be done in consultation with other authorities, and the final decision is made by the President. This ensures a system of checks and balances and prevents sole authority from being concentrated in one individual or institution.
