The correct answer is: D. Panchayat Samiti
The Panchayat Samiti is an intermediate tier in the Panchayati Raj system. It is a local government body that is responsible for the development of a group of villages. The Panchayat Samiti is headed by a president, who is elected by the members of the Panchayat Samiti. The Panchayat Samiti has a number of functions, including:
- Planning and implementing development schemes
- Providing basic services to the people
- Maintaining law and order
- Promoting education and health
The Panchayat Samiti is an important part of the Panchayati Raj system. It helps to bring about development at the local level and to empower the people.
The other options are incorrect because:
- Gram Panchayat is the lowest tier in the Panchayati Raj system. It is responsible for the development of a single village.
- Zila Parishad is the highest tier in the Panchayati Raj system. It is responsible for the development of a district.
- Sarpanch is the head of a Gram Panchayat.
