The correct answer is (c), Dunagiri.
The Kosi River is a major river in the Indian subcontinent. It originates in the Garhwal Himalayas in Uttarakhand, India, and flows through Nepal and India before emptying into the Bay of Bengal. The river is about 700 kilometers (435 mi) long, and its drainage basin covers an area of about 100,000 square kilometers (39,000 sq mi).
The Kosi River is a major source of water for irrigation and drinking water in the region. However, the river is also prone to flooding, which has caused extensive damage in the past.
The origin of the Kosi River is a glacier on the slopes of the Dunagiri peak in the Garhwal Himalayas. The glacier melts in the summer, and the water flows down the mountainside to form the river. The Kosi River then flows through the plains of Nepal and India before emptying into the Bay of Bengal.
