The correct answer is: d) All of the above.

Gram Panchayats are the smallest unit of local self-government in India. They are responsible for a wide range of functions, including sanitation and drinking water, street lighting, maintenance of local roads, and other infrastructure.

Sanitation and drinking water are essential for public health and well-being. Gram Panchayats are responsible for ensuring that all households have access to safe drinking water and adequate sanitation facilities. They do this by constructing and maintaining water supply and sanitation infrastructure, and by providing awareness and education on hygiene and sanitation.

Street lighting is important for safety and security. Gram Panchayats are responsible for installing and maintaining street lights in all public areas, including streets, parks, and markets. This helps to reduce crime and accidents, and makes it safer for people to move around at night.

Maintenance of local roads is essential for ensuring that people can travel safely and easily. Gram Panchayats are responsible for repairing and maintaining roads, drains, and other infrastructure. They also undertake periodic road widening and construction projects to improve connectivity and reduce traffic congestion.

In addition to these core functions, Gram Panchayats are also responsible for a range of other activities, such as promoting education, health, and social welfare; providing employment opportunities; and promoting economic development. They play a vital role in the lives of rural communities and help to improve the quality of life for all.
