Which one of the following authorities recommends the principles governing the grants-in-aid of the revenues to the states out of the Consolidated Fund of India?

1. The question asks which authority recommends the principles governing the grants-in-aid of the revenues to the states out of the Consolidated Fund of India. 2. Article 280 of the Indian Constitution provides for the establishment of a Finance Commission. 3. One of the key duties of the Finance Commission, as mandated by Article 280(3)(b), is to make recommendations to the President regarding 'the principles which should govern the grants-in-aid of the revenues of the States out of the Consolidated Fund of India'. 4. These grants-in-aid are provided under Article 275 of the Constitution. 5. The Interstate Council (B) deals with inter-state coordination. The Union Ministry of Finance (C) implements the recommendations but doesn't set the governing principles independently. The Public Accounts Committee (D) is a parliamentary committee that examines government expenditure. 6. Therefore, the Finance Commission (Option A) is the constitutional authority responsible for recommending these principles.
