Show answer
Explanation
The correct answer is B, the Yamuna. The Yamuna comes down from Yamunotri, enters Haryana near Kalesar in Yamunanagar district and flows south along the eastern boundary of the state with Uttar Pradesh and Delhi. It is the only river in Haryana that carries water through the year, which is why the Hathnikund barrage and the canals drawn from it matter so much to the state's irrigation.
Option A, the Ghaggar, is the longest river inside Haryana but it is seasonal: it fills in the monsoon and runs as a sandy channel for the rest of the year, finally dying in the sands of Rajasthan. Option C, the Markanda, is a Shivalik stream and a tributary of the Ghaggar, dry outside the rains. Option D, the Sahibi, rises in the Aravalli of Rajasthan and reaches the Najafgarh jheel only in flood. The point to keep is the contrast: one perennial Himalayan river on the edge of the state, and seasonal streams everywhere else.
