The correct answer is: A. Nawada, Nalanda, Sheikhpura.
The Sakri Nata river interlinking scheme is a proposed project to link the Sakri and Nata rivers in the Indian state of Bihar. The project aims to provide irrigation and drinking water to the districts of Nawada, Nalanda, and Sheikhpura.
The Sakri river is a tributary of the Ganges River, while the Nata river is a tributary of the Son River. The two rivers are located in the north-central part of Bihar.
The project is estimated to cost Rs. 1,000 crore. It is expected to be completed in five years.
The project has been opposed by some environmental groups, who argue that it will have a negative impact on the environment. However, the government has said that the project will be implemented in a way that minimizes environmental impact.
The Sakri Nata river interlinking scheme is one of several river interlinking projects that are being proposed in India. These projects aim to improve water management in the country.
The other options are incorrect because they do not include the districts of Nawada, Nalanda, and Sheikhpura.
