The correct answer is: A) Gram Panchayat.
A Gram Panchayat is the smallest unit of local government in Kerala. It is a self-governing body that is responsible for the development and welfare of the people living in its jurisdiction. The Gram Panchayat is elected by the people of the village and is headed by a President. The Gram Panchayat has a number of functions, including:
- Providing basic amenities such as water, sanitation, and electricity
- Promoting education and health
- Maintaining law and order
- Promoting economic development
The Gram Panchayat is an important institution in the Kerala government. It is responsible for providing basic services to the people and for promoting development at the grassroots level.
The other options are incorrect because they are not the smallest unit of local government in Kerala. A Block Panchayat is a group of Gram Panchayats, a District Panchayat is a group of Block Panchayats, and a Zilla Parishad is a group of District Panchayats.
