The correct answer is B. Gaya.
The Eastern Sone Canal is a canal system in India that irrigates parts of the states of Bihar and Jharkhand. It is a branch canal of the Sone River, and it was constructed in the early 20th century. The canal system is about 250 kilometers long, and it irrigates an area of about 1.5 million hectares.
The canal system is divided into two parts: the upper canal and the lower canal. The upper canal is about 150 kilometers long, and it irrigates an area of about 750,000 hectares. The lower canal is about 100 kilometers long, and it irrigates an area of about 750,000 hectares.
The canal system is used to irrigate a variety of crops, including rice, wheat, sugarcane, and maize. The canal system also provides water for drinking and industrial purposes.
The Eastern Sone Canal is an important source of irrigation for the states of Bihar and Jharkhand. The canal system helps to improve agricultural productivity and to provide water for drinking and industrial purposes.
The other options are incorrect because they are not districts that are irrigated by the Eastern Sone Canal.
