Step 1: Understanding the Question
The question asks to identify the highest-ranking law officer of the Government of India, often referred to as the first legal officer of the country.
Step 2: Analyzing the Roles of Legal Officers
(A) Attorney General for India: This is a constitutional post created under Article 76. The Attorney General is the chief legal advisor to the Government of India and its primary lawyer in the Supreme Court. They are appointed by the President and hold the highest rank among law officers in the country.
(B) Solicitor General of India: The Solicitor General is the second-highest law officer in the country. They assist the Attorney General and are considered a statutory post, not a constitutional one.
(C) Advocate General of the State: This is a constitutional post (under Article 165) analogous to the Attorney General, but at the state level. The Advocate General is the highest law officer of a state government.
(D) State Attorney: This is a general term and not a specific high-ranking office in the Indian legal system.
Step 3: Final Answer
The Attorney General for India is the first and highest legal officer of the country. Therefore, option (A) is the correct answer.
