Which river is one of the major Himalayan tributaries of Yamuna and comes from Uttarakhand?

Correct answer: Tons

The governing concept is the drainage pattern of the Yamuna and the distinction between Himalayan and peninsular rivers. The Tons is a major Himalayan tributary of the Yamuna and rises in the Uttarakhand region before joining the Yamuna system. Consequently, option A is correct. Musi is associated with Hyderabad and belongs to the Krishna drainage system. Luni is a largely seasonal river of the arid western region, and Bhima is an important tributary of the Krishna in peninsular India. The clues “Himalayan,” “Uttarakhand” and “tributary of Yamuna” must be considered together; they rule out the southern and western rivers. Tons is therefore the geographically consistent choice.
