b. Chambal
c. Luni
d. Betwa
e. None of these

Answer 1

Hint:
 In 1892, Maharaja Jaswant Singh of Jodhpur developed Jaswant Sagar in Pichiyak town among Bilara and Bhavi of Jodhpur area. It is one of the biggest artificial lakes in India, and irrigates in excess of 12,000 acres of land (49 km sq.).


Complete solution:
Luni is the biggest river in the Thar desert in north-west India. It starts in the Pushkar valley of the Aravalli Range, close to Ajmer, goes through the southeastern part of the Thar Desert, and finishes in the boggy grounds of Rann of Kutch in Gujarat, subsequent to voyaging separation of 495 km. It is first known as Sagarmati, at that point subsequent to passing Govindgarh, it meets its feeder Saraswati, which begins from Pushkar Lake, and from that point on it gets its name Luni.

The Luni River bowl is 37,363 km², which incorporates all or part of the Ajmer, Barmer, Jalore, Jodhpur, Nagaur, Pali, and Sirohi areas of Rajasthan and the Banaskantha and Patan locale of northern Gujarat. Its significant feeders are the Sukri, Mithril River, Bandi, Khari, Jawai, Guhiya, and Sagi from the left, and the Jojari from the right.

The Luni River starts close to Ajmer in the Pushkar valley of the western Aravalli Range at a height of about 550m. Now, the river is otherwise called the Sabarmati. The stream at that point streams the southwest way through the slopes and fields of the Marwar district in Rajasthan. The stream flows south-west and enters the Thar Desert prior to dispersing into the Rann of Kutch, navigating a sum of 495 km. Despite the high saltiness, it is a significant river in the district and fills in as an essential wellspring of the water system. The Luni isn't saline until it arrives at Balotra, where a high salt substance in the dirt affects the river.

The Luni river has been the southern part of the notable Ghaggar-Hakra river channel.

Hence, the correct answer is option C.

Note:
The Jawai, Sukri, Guhiya, Bandi, and Jojari streams are the fundamental feeders of the Luni river. The Jojari is the main feeder that converges to one side bank of the stream while the other 10 feeders arrive at its left bank. All the feeders with the exception of Jojari begin from the Aravalli slope.
