Correct Answer: Bihar

Solution : The correct answer is (a) Bihar

According to the latest estimates by NITI Aayog, 42.1 % of the population of Bihar lives below the poverty line. This is followed by Uttar Pradesh 32.9 %, Maharashtra 19.7 % , and West Bengal 14.7 %.

The poverty line in India is defined as the minimum income or consumption level that is necessary to meet basic needs. The poverty line is different for rural and urban areas. In 2017-18, the poverty line for rural areas was Rs. 1000 per month and Rs. 1100 per month for urban areas.

The high levels of poverty in Bihar can be attributed to a number of factors, including low levels of education, lack of employment opportunities, and poor infrastructure. The state has also been affected by natural disasters such as floods and droughts.
