The Budhil and the Tundahen are the tributaries of which river?

The correct answer is option 4: Ravi

Bharmaur region: This region popularly known as the homeland of Gaddis is surrounded by lofty mountains on all sides. It has Pir Panjal in the north and Dhaula Dhar in the south. In the east, the extension of Dhaula Dhar converges with Pir Panjal near Rohtang Pass. The river Ravi and its tributaries– the Budhil and the Tundahen, drain this territory and carve out deep gorges.
