The correct answer is: D. All of the above.
The Panchayati Raj System of Government is a three-tier system of local self-government in India. It consists of Gram Panchayats (village councils), Panchayat Samitis (block councils), and Zila Parishads (district councils). The system was established in 1992 with the passage of the 73rd and 74th Constitutional Amendments.
The Panchayati Raj System aims to give social and economic justice to villages. It does this by devolving power to the local level and by involving people in decision-making. The system also aims to promote development and to improve the quality of life in rural areas.
Some members of Parliament are representatives in Zila Parishads. This is because Zila Parishads are the highest tier of the Panchayati Raj System. They are responsible for planning and implementing development programs at the district level.
In conclusion, the Panchayati Raj System of Government is a three-tier system of local self-government in India. It aims to give social and economic justice to villages by devolving power to the local level and by involving people in decision-making. Some members of Parliament are representatives in Zila Parishads.
