Step 1: Concept Identification: The query concerns the powers and responsibilities conferred upon Panchayats by the 73rd Constitutional Amendment Act, 1992, as detailed in Part IX of the Constitution.
Step 2: Statement Analysis: Each assertion is evaluated against constitutional provisions:
- (A) Economic Development Planning: Article 243G mandates that state legislatures may empower Panchayats with the ability to function as self-governing institutions, including the preparation of economic development plans. This is a correct power.
- (B) Social Justice Promotion: Article 243G also designates the promotion of social justice schemes as a principal responsibility of Panchayats. This is a correct power.
- (C) Revenue Collection: Article 243H empowers state legislatures to authorize Panchayats to levy, collect, and appropriate taxes, duties, tolls, and fees. This is a correct power.
- (D) Devolution of Responsibilities: This statement describes the objective or principle underpinning the Panchayati Raj system, rather than a direct power granted *to* a Panchayat. Panchayats are recipients of devolution, not its facilitators. The state government and the State Finance Commission are responsible for this process. Thus, this is not a direct Panchayat power.
Step 3: Conclusion: The direct powers and responsibilities delegated to Panchayats are represented by statements (A), (B), and (C).
