Certainly! Let me explain each statement regarding the Attorney-General of India:

I. He is appointed by the President of India:

This statement is correct. The Attorney-General of India is appointed by the President of India. The President holds the authority to appoint the Attorney-General under Article 76(1) of the Indian Constitution.

II. He must have the same qualifications as are required for a Judge of the Supreme Court:

This statement is also correct. According to Article 76(1) of the Indian Constitution, the Attorney-General of India must possess the same qualifications as those required for a Judge of the Supreme Court. This includes being a citizen of India and having been a judge of a high court for at least five years or an advocate of a high court for at least ten years or an eminent jurist.

III. He must be a member of either House of Parliament:

This statement is incorrect. There is no specific requirement for the Attorney-General of India to be a member of either House of Parliament. Unlike ministers in the government, the Attorney-General is not required to be a member of Parliament.

IV. He can be removed by impeachment by Parliament:

This statement is also incorrect. The Attorney-General of India does not hold a tenure subject to impeachment by Parliament. The Attorney-General serves at the pleasure of the President and can be removed from office by the President at any time.

Therefore, the correct statements are I. He is appointed by the President of India and II. He must have the same qualifications as are required for a Judge of the Supreme Court.
