The correct answer is: a) Mission Shakti.
Mission Shakti is a flagship program of the Government of India launched in 2015 to empower women through Self-Help Groups (SHGs). The program aims to provide financial assistance, training, and other support to SHGs so that they can become self-reliant and contribute to the economic development of the country.
Swachh Bharat Mission is a cleanliness campaign launched in 2014 to make India open defecation-free. The campaign focuses on construction of toilets, awareness generation, and behavior change.
PMGSY is a rural roads program launched in 2000 to provide all-weather connectivity to rural areas. The program has helped to improve connectivity and reduce travel time for rural people.
PMAY-G is a housing for all scheme launched in 2015 to provide affordable housing to the poor. The scheme has helped to improve the living conditions of the poor and reduce the number of people living in slums.
In conclusion, Mission Shakti is the only program that specifically focuses on empowering women through SHGs. The other programs have different objectives and do not specifically focus on women.
