The correct answer is: D. Sheohar
Sheohar is the poorest district in Bihar according to per capita income criteria. The per capita income of Sheohar is Rs. 22,604, which is the lowest among all the districts in Bihar. The per capita income of Bihar is Rs. 30,114, which is also the lowest among all the states in India.
The per capita income of a district is calculated by dividing the total income of the district by the total population of the district. The total income of a district is calculated by adding up the incomes of all the individuals in the district. The total population of a district is calculated by adding up the populations of all the villages and towns in the district.
The per capita income of a district is an important indicator of the economic development of the district. A high per capita income indicates that the district is economically developed, while a low per capita income indicates that the district is economically underdeveloped.
The per capita income of Sheohar is low because the district is economically underdeveloped. The main reasons for the economic underdevelopment of Sheohar are:
- The lack of industries in Sheohar.
- The lack of infrastructure in Sheohar.
- The lack of education in Sheohar.
- The lack of healthcare in Sheohar.
The government of Bihar has taken some steps to improve the economic development of Sheohar. These steps include:
- Setting up new industries in Sheohar.
- Improving the infrastructure in Sheohar.
- Improving the education in Sheohar.
- Improving the healthcare in Sheohar.
However, these steps have not been enough to improve the economic development of Sheohar. The government of Bihar needs to take more steps to improve the economic development of Sheohar.
