The correct answer is A. Mewat (Nuh).
Mewat (Nuh) has the lowest literacy rate in Haryana, with 56.6% of the population being literate. This is significantly lower than the state average of 76.6%. There are a number of factors that contribute to the low literacy rate in Mewat, including poverty, lack of access to education, and social and cultural barriers.
Poverty is a major problem in Mewat, and many families cannot afford to send their children to school. In addition, there are a shortage of schools in the district, and those that do exist are often overcrowded and poorly equipped. This makes it difficult for children to receive a quality education.
Social and cultural barriers also contribute to the low literacy rate in Mewat. Many families in the district believe that girls do not need to be educated, and they often marry them off at a young age. This prevents girls from getting an education and also contributes to the high rate of female illiteracy in the district.
The government has taken a number of steps to improve the literacy rate in Mewat, including building new schools, providing scholarships to students, and launching awareness campaigns. However, more needs to be done to address the root causes of the problem.
