A government program to improve the availability of food grains in Mizoram is:

Antyodaya Anna Yojana
Midday Meal Scheme
Targeted Public Distribution System (TPDS)
Prime Minister Garib Kalyan Anna Yojana

The correct answer is: c) Targeted Public Distribution System (TPDS).

The Targeted Public Distribution System (TPDS) is a government program in India that provides subsidized food grains to poor households. The program was launched in 1997 and is implemented by the Ministry of Consumer Affairs, Food and Public Distribution.

The TPDS is a targeted program, which means that it is only available to households that are below the poverty line. Households are eligible for the TPDS if they are enrolled in the Antyodaya Anna Yojana (AAY), which is a government program that provides food grains to the poorest households in India.

The TPDS provides food grains at a subsidized price to eligible households. The price of food grains under the TPDS is lower than the market price. The subsidy on food grains is provided by the government.

The TPDS is a major source of food for poor households in India. The program provides food grains to over 700 million people in India. The TPDS has been successful in reducing hunger and malnutrition in India.

The other options are incorrect because they are not government programs to improve the availability of food grains in Mizoram.

b) Midday Meal Scheme is a government program that provides free meals to school children in India. The program is not specific to Mizoram.

d) Prime Minister Garib Kalyan Anna Yojana is a government program that provides food grains to poor households in India. The program is not specific to Mizoram.
