The Sant Namdev National Award is given to an individual who promotes:

Communal Harmony
Classical Music
Folk Arts
Social Justice

The Sant Namdev National Award is given to an individual who promotes communal harmony. It is a prestigious award given by the Government of India to individuals who have made significant contributions to the promotion of communal harmony in India. The award is named after Sant Namdev, a 13th-century Hindu saint who was known for his message of peace and tolerance.

Communal harmony is the state of peaceful coexistence among people of different religious, ethnic, or cultural backgrounds. It is essential for the development of a society as it promotes tolerance, understanding, and respect for diversity. Communal harmony can be promoted through various means, such as education, interfaith dialogue, and community outreach programs.

The Sant Namdev National Award is a significant recognition of the importance of communal harmony in India. It is a reminder that we must all work together to create a society where everyone can live in peace and harmony.

The other options are incorrect because they do not directly relate to the promotion of communal harmony. Classical music, folk arts, and social justice are all important aspects of Indian culture, but they do not necessarily promote communal harmony.
