The correct answer is option 3: Gram Sabha. Gram Sabha is an example of direct democracy in India. In a Gram Sabha, all members of a village who are above the age of 18 have the right to participate in decision-making processes. They can discuss and decide on matters that affect the village, such as approving budgets, determining development priorities, and electing members to the Gram Panchayat. This form of direct democracy allows every member to have an equal say in the decision-making process. Zila Panchayat (option 1) and Kshetra Panchayat (option 4) are examples of representative democracy, where selected representatives make decisions on behalf of the people. Nagar Panchayat (option 2) is a local urban government body, where decisions are made by elected representatives.
