The correct answer is: a) Pradhan Mantri Gram Sadak Yojana (PMGSY).
The Pradhan Mantri Gram Sadak Yojana (PMGSY) is a centrally sponsored scheme launched by the Government of India in 2000 to provide road connectivity to all rural habitations in the country. The scheme is implemented by the Ministry of Rural Development.
The PMGSY aims to provide all-weather road connectivity to all rural habitations with a population of 500 or more and a distance of 5 km or more from a metalled road. The scheme also provides connectivity to habitations with a population of less than 500 if they are located in difficult areas.
The PMGSY has been a major success in improving road connectivity in rural India. As of March 2019, the scheme has constructed over 1.25 lakh km of roads in rural areas. This has helped to improve the mobility of people and goods in rural areas, and has also had a positive impact on the socio-economic development of rural areas.
