The correct answer is (c), Balwantrai Mehta Committee.
The Balwantrai Mehta Committee was a committee set up by the Government of India in 1957 to study the working of the Community Development Programme (CDP) and to suggest measures for its improvement. The Committee submitted its report in 1958, and one of its major recommendations was the establishment of a three-tier Panchayati Raj system.
The three-tier Panchayati Raj system consists of village panchayats, block panchayats, and district panchayats. The village panchayat is the lowest tier, and it is responsible for local development and welfare activities. The block panchayat is the middle tier, and it is responsible for coordinating the activities of the village panchayats in the block. The district panchayat is the highest tier, and it is responsible for planning and development activities at the district level.
The Panchayati Raj system has been in existence since the 1960s, and it has been instrumental in promoting local democracy and development in India. The system has been praised for its ability to bring about decentralisation and to empower local communities. However, the system has also been criticised for its lack of effectiveness and for its failure to address the needs of the poor.
