Attorney General of India

The correct answer is Option 4 - Attorney General of India

Article 76 of the Constitution of India deals with the office of the Attorney General for India.

According to Article 76, the President of India appoints the Attorney General of India, who is the highest legal officer of the government. The Attorney General is appointed to provide legal advice to the government on various matters and to represent the government in legal proceedings.
The Attorney General must be qualified to be appointed as a judge of the Supreme Court. However, the Constitution does not specify any particular qualifications or experience required for the position.
Unlike other constitutional functionaries such as judges of the Supreme Court and the Comptroller and Auditor General of India, the Attorney General does not have a fixed tenure. They hold office at the pleasure of the President, which means they can be removed by the President at any time.
The primary role of the Attorney General is to provide legal advice to the government of India on matters of law and to represent the government in legal proceedings in the Supreme Court.
