An initiative to strengthen Gram Sabhas and promote participatory democracy in Tamil Nadu is:

Naan Mudhalvan
Pudhu Vaazhvu Project
Illam Thedi Kalvi
Makkalai Thedi Maruthuvam

The correct answer is Pudhu Vaazhvu Project.

Pudhu Vaazhvu Project is an initiative of the Government of Tamil Nadu to strengthen Gram Sabhas and promote participatory democracy. The project aims to empower the people at the grassroots level by providing them with information and resources, and by encouraging them to participate in decision-making.

The project has been implemented in all the districts of Tamil Nadu. It has been successful in mobilizing the people and in making them aware of their rights and responsibilities. The project has also helped to improve the functioning of the Gram Sabhas.

The following are the other options:

  • Naan Mudhalvan is a Tamil Nadu government initiative to provide financial assistance to first-time entrepreneurs.
  • Illam Thedi Kalvi is a Tamil Nadu government initiative to provide free education to children from poor families.
  • Makkalai Thedi Maruthuvam is a Tamil Nadu government initiative to provide free medical treatment to children from poor families.

These initiatives are important for the development of Tamil Nadu. However, they are not directly related to strengthening Gram Sabhas and promoting participatory democracy.
