The correct option is A Panchayati Raj
Panchayat Raj system can be defined as the decentralization of administration. It aims at giving authority to the local people to participate in administration and take decisions. Though ancient India had a tradition of local self-government, after independence, the system was given constitutional mandate. In 1955, the Central government formed a committee under the chairmanship of Balwantrai Mehta. This committee recommended a three-tier local administration system.
