The ambitious scheme launched in June 2011 by Government of India to provide free health care facilities to pregnant women and infants has been named as

Indira Gandhi Matritiva Sahyog Yojna
Janani SurakshaYojana
Jannai Shishu, Suraksha Karyakram
Integrated Child Development Scheme

The correct answer is (b) Janani Suraksha Yojana.

Janani Suraksha Yojana (JSY) is a government of India scheme launched in 2005 to reduce maternal and infant mortality rates. It provides free cash incentives to pregnant women who deliver their babies in institutional facilities. The scheme also provides free transportation to and from the hospital, as well as free food and medicines.

JSY is one of the largest government-funded health programs in India. It has been credited with helping to reduce maternal mortality rates by 28% and infant mortality rates by 18% since its inception.

The scheme is implemented by the Ministry of Health and Family Welfare through the state governments. It is open to all pregnant women who are below the poverty line. To be eligible for the scheme, women must register with a government health facility at least 12 weeks before their due date.

JSY provides a cash incentive of Rs. 1,400 to women who deliver their babies in institutional facilities. The incentive is paid in two installments: Rs. 600 at the time of registration and Rs. 800 after delivery.

The scheme also provides free transportation to and from the hospital for pregnant women who live more than 5 kilometers from a government health facility. Women who are unable to walk to the hospital are also provided with free ambulance services.

JSY also provides free food and medicines to pregnant women who are admitted to government health facilities. The food provided includes a nutritious diet that is tailored to the needs of pregnant women. The medicines provided include those that are essential for the health of the mother and the baby.

JSY is a comprehensive health program that has been successful in reducing maternal and infant mortality rates in India. It is a valuable resource for pregnant women and their families.

The other options are incorrect because they are not government-funded health programs that provide free cash incentives to pregnant women who deliver their babies in institutional facilities.
