The correct answer is (a) South Salmara-Mankachar.
South Salmara-Mankachar is a district in the Indian state of Assam. It is the newest district of Assam, having been carved out of Dhubri district in 2012. The district has a population of 233,479 and a literacy rate of 57.05%. The district is predominantly rural, with only 10% of the population living in urban areas. The main languages spoken in the district are Assamese, Bengali, and Hindi.
The low literacy rate in South Salmara-Mankachar is due to a number of factors, including poverty, lack of access to education, and gender inequality. The district has a high incidence of poverty, with over 50% of the population living below the poverty line. This lack of economic resources makes it difficult for families to send their children to school. In addition, the district has a shortage of schools and teachers. This shortage is particularly acute in rural areas, where many children have to walk long distances to attend school. Finally, gender inequality is also a major factor in the low literacy rate. In South Salmara-Mankachar, girls are less likely than boys to attend school. This is due to a number of factors, including social norms that discourage girls from pursuing education.
The low literacy rate in South Salmara-Mankachar has a number of negative consequences. It limits the economic opportunities of the population and contributes to poverty. It also makes it difficult for people to participate in democratic processes and to access information and services. The government of Assam has taken a number of steps to address the problem of low literacy in the state. These include the construction of new schools, the recruitment of more teachers, and the provision of scholarships and other financial assistance to students. However, more needs to be done to improve the literacy rate in South Salmara-Mankachar.
