Step 1: Advocate-General's Role:
The Advocate-General is the state government's top legal advisor, mirroring the Attorney General of India at the central level. Their primary function is to provide legal counsel to the state.
Step 2: Constitutional Basis:
Article 165 of the Indian Constitution governs the Advocate-General's appointment, responsibilities, and term.
Article 165(1) specifies: "The Governor of each State shall appoint a person qualified to be a High Court judge as the Advocate-General for the State."
Step 3: Option Analysis:
(A) Chief Justice of India: The CJI leads the Indian judiciary and participates in judicial appointments, but not the state's Advocate-General.
(B) Chief Justice of High Court: The High Court's Chief Justice heads the state judiciary. While Advocate-Generals must be High Court judge-eligible, the Chief Justice doesn't appoint them.
(C) Governor of the State: Article 165 grants the state Governor the appointment power. This is the correct choice.
(D) President of India: The President appoints the Attorney General for India (the Union's top legal officer), not state Advocate-Generals.
Step 4: Conclusion:
The Governor of the State appoints the Advocate-General for a state.
