Who can be appointed as a Judge of the Supreme Court?

According to Article 124(3) of the Constitution of India, a person is qualified for appointment as a Judge of the Supreme Court if they are a citizen of India and meet one of three specific criteria: (a) they have been a Judge of a High Court (or two or more such courts in succession) for at least five years; (b) they have been an advocate of a High Court (or two or more such courts in succession) for at least ten years; or (c) they are, in the opinion of the President, a distinguished jurist. Option 1 is incorrect because it specifies 'any court' instead of a High Court. Option 2 is incorrect as the requirement is five years, not three. Option 4 is incorrect as 'judicial office' for ten years is a qualification for High Court judges, not the Supreme Court.
