The correct answer is (a) 1992.
The Indira Gandhi Matritva Sahyog Yojana (IGMSY), also known as the Manila Samridhi Yojana, is a government of India scheme launched in 1992 to provide financial assistance to pregnant women and lactating mothers. The scheme is implemented by the Ministry of Women and Child Development and is aimed at reducing maternal and infant mortality rates.
The scheme provides a cash incentive of Rs. 1,000 to pregnant women who complete their full term of pregnancy and Rs. 600 to lactating mothers who exclusively breastfeed their babies for six months. The scheme is also linked to the Janani Suraksha Yojana (JSY), which provides free medical care to pregnant women.
The IGMSY has been successful in reducing maternal and infant mortality rates in India. The scheme has also helped to improve the nutritional status of mothers and children.
The other options are incorrect because the Indira Gandhi Matritva Sahyog Yojana was not started in those years.
