Answer 1

it means the following
In India, the Panchayati Raj generally refers to the system of local self-government in India introduced by a constitutional amendment in 1992, although it is based upon the traditional panchayat system of South Asia. This Panchayati Raj system was formalized in 1992, following a study conducted by a number of Indian committees on various ways of implementing more decentralized administration. The modern Panchayati Raj and its Gram Panchayats are not to be confused with the extra-constitutional KhapPanchayats (or Caste Panchayats) found in northern India.[1]

In India, the Panchayati Raj now functions as a system of governance in which gram panchayats are the basic units of local administration. The system has three levels: Gram Panchayat (village level), Mandal Parishad or Block Samiti or Panchayat Samiti (block level), and Zila Parishad (district level).[2] It was formalized in 1992 by the 73rd amendment to the Indian Constitution.[3]Currently, the Panchayati Raj system exists in all states except Nagaland, Meghalaya, and Mizoram, and in all Union Territories except Delhi.[4]
