The correct answer is: B. Punpun
The Punpun is a river in India that flows through the states of Bihar and Jharkhand. It is a tributary of the Ganges River. The Punpun originates in the hills of Jharkhand and flows eastward through the plains of Bihar. It joins the Ganges River at Fatuha, about 20 kilometers north of Patna. The Punpun is a perennial river, but its flow varies greatly throughout the year. It is at its fullest during the monsoon season, when it receives heavy rains from the Himalayas. During the dry season, the Punpun can become a trickle.
The Punpun is an important source of water for irrigation and drinking water. It is also a popular destination for fishing and boating. The river is home to a variety of fish species, including carp, catfish, and tilapia. The Punpun is also home to a number of birds, including herons, egrets, and kingfishers.
The Punpun is a beautiful river with a rich history and culture. It is a popular tourist destination and a valuable resource for the people of Bihar and Jharkhand.
The other options are incorrect because they are not tributaries of the Ganges River. The Son River is a tributary of the Ganges River, but it does not join the Ganges River at Fatuha. The Sakri River is a tributary of the Son River, and the Kamla Balan River is a tributary of the Sakri River.
