The primary government scheme providing subsidized food grains to low-income families in Karnataka:

Antyodaya Anna Yojana
Targeted Public Distribution System (TPDS)
Midday Meal Scheme
Integrated Child Development Services (ICDS)

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

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

The TPDS is a ration card-based system. Households that are eligible for the program are issued ration cards, which they can use to purchase food grains at subsidized prices from ration shops. The prices of food grains under the TPDS are lower than the market prices.

The TPDS is a major source of food for low-income families in India. The program provides food security to millions of people and helps to reduce poverty and hunger.

The other options are incorrect because:

  • Antyodaya Anna Yojana (AAY) is a poverty alleviation program that provides food grains to the poorest of the poor.
  • Midday Meal Scheme is a school meal program that provides free meals to children in government and government-aided schools.
  • Integrated Child Development Services (ICDS) is a child care program that provides services such as nutrition, health care, and education to children under the age of six.
