The correct answer is: 5 kg.
The National Food Security Act (NFSA) is a legislation enacted by the Government of India in 2013. The Act guarantees food and nutritional security to all Indian citizens by providing them with subsidized food grains. Under the NFSA, priority households in Odisha are entitled to receive 5 kg of rice per month at a subsidized rate of Rs. 2/- per kg.
The other options are incorrect because they do not correspond to the number of kilograms of rice that priority households in Odisha are entitled to receive under the NFSA.
