The correct answer is option 2: Attorney General. The Attorney General is the first law officer of the country. This position is responsible for giving legal advice to the government and representing the government in legal matters. The Attorney General is appointed by the President of India and holds office during the pleasure of the President. They have the authority to appear in courts on behalf of the government and participate in important cases. It is important to note that while the Chief Justice of India is a prominent figure in the Indian legal system, they are not considered the first law officer. The Chief Justice of India is the highest-ranking judge in the Supreme Court of India, and their role is primarily judicial rather than advising the government.
