Solution:In 2013, NFSA was enacted to provide food security to 67% of the population in the form of highly subsidized food grains at Rs. 2 and 3 per Kg for wheat and rice respectively. The coverage under NFSA has been delinked from poverty estimates. So, #1 is wrong.Pregnant women and lactating mothers are entitled to a nutritious "take home ration" of 600 Calories and a maternity benefit of at least Rs 6,000 for six months. So #3 is wrong.
Thus, by elimination, we are left with correct answer B: only 2.
NFSA covers upto 75% of the rural population and 50% of the urban population under under Antyodaya Anna Yojana (AAY) and priority households. While AAY households, which constitute poorest of the poor are entitled to 35 kg of foodgrains per family per month, priority households are entitled to 5 kg per person per month. Corresponding to the all India coverage of 75% and 50% in the rural and urban areas, State-wise coverage under NFSA was determined by the erstwhile Planning Commission (now NITI Aayog) by using the NSS Household Consumption Survey data for 2011-12. Within the coverage under TPDS determined for each State, the work of identification of eligible households is to be done by States/UTs.
