The government program focused on providing nutritional support to pregnant women and children:

POSHAN Abhiyaan
Integrated Child Development Services
Midday Meal Scheme
Public Distribution System

The correct answer is: A) POSHAN Abhiyaan

POSHAN Abhiyaan is a national nutrition mission launched by the Government of India in 2018. The mission aims to improve the nutritional status of children, pregnant women, and lactating mothers. It focuses on providing nutritional support, improving access to healthcare, and creating awareness about nutrition.

The Integrated Child Development Services (ICDS) is a government program that provides early childhood care and education, nutrition, and health services to children under the age of six and their mothers. The program is implemented through Anganwadi centers, which are located in rural and urban areas.

The Midday Meal Scheme is a government program that provides free cooked meals to children in government and government-aided schools. The scheme aims to improve the nutritional status of children and to increase school attendance.

The Public Distribution System (PDS) is a government program that provides subsidized foodgrains to ration card holders. The scheme aims to ensure food security for the poor and vulnerable sections of the population.

POSHAN Abhiyaan is a more recent program than the other three options, and it is specifically focused on nutrition. The other three programs are broader in scope, and they do not have the same focus on nutrition.
