The correct answer is (a) Malkangiri.
Malkangiri is a district in Odisha, India. It is the easternmost district of the state and is bordered by Andhra Pradesh to the north, Chhattisgarh to the east, and the state of Jharkhand to the south. The district has a population of over 1.2 million people and is one of the most backward districts in Odisha.
The literacy rate in Malkangiri is 47.2%, which is the lowest in the state. This is due to a number of factors, including poverty, lack of education facilities, and social backwardness. The district has a high number of tribal people, who are often marginalized and have limited access to education.
The government has taken a number of initiatives to improve the literacy rate in Malkangiri. These include setting up new schools, providing scholarships to students, and launching awareness campaigns. However, more needs to be done to improve the situation.
