The correct answer is: Eastern Sone Canal.
The Eastern Sone Canal is a canal system in Bihar, India. It is a branch of the Sone River and is used for irrigation and drinking water. The canal system was built in the 19th century and is one of the largest canal systems in India. It covers an area of over 10,000 square kilometers and irrigates over 2 million hectares of land. The canal system also provides drinking water to over 10 million people.
The Eastern Sone Canal is divided into two main branches: the Eastern Sone Canal Main Line and the Eastern Sone Canal Branch Canal. The Eastern Sone Canal Main Line is the main branch of the canal system and is about 200 kilometers long. The Eastern Sone Canal Branch Canal is a smaller branch of the canal system and is about 100 kilometers long.
