Question

A) Banganga
B) Saab
C) Menda
D) All of these

Answer 1

Hint:
Rajasthan is the biggest state in an area with 5.5 per cent population but only 1 per cent water reserves of the country. The state is distributed into 13 watersheds and 59 sub-watersheds. Most of the Rivers begin from the Aravali hills and flow either in east or west. Those Rivers flowing in the east merge with the Yamuna. Those flowing west fall into the Gulf of Khambhat or are lost in the desert.

Complete solution:
 Chambal is the main perpetual River of the state, which enters Rajasthan at Chauragarh, in the wake of beginning from the northern slopes of the Vindhya Range. This river flows along the eastern border between Rajasthan and Madhya Pradesh. Fed by its branches, Chambal flows northwards across the state and joins the Yamuna River. The inland drainage system is the considerably characteristic feature of the drainage system of Rajasthan which is that nearly 2 percent of the area of the state. Almost all this area lies west of the Aravalli range. In this part of Kanti basin, Sota and Sahibi basin, Barah basin of the Luni basin are found in a large number of distinct drainage basins. The desert path in the western part drains all the water of these rivers. There are various Rajasthan rivers, which flow across the state.
There are several Rajasthan rivers, which flow across the state. Most of these rivers are seasonal. Ghaggar is the intermittent river which moves through Rajasthan and vanishes at the core of the Thar Desert. A part of the other enormous Rajasthan Rivers is Kali, Banas, Banganga, Parvati, Gambhir, Mahi, Kakni, Jokham, Sabarmati, Katli, Sabi and Mantha.

Hence, the correct answer is option D.

Note:
 The southern and the eastern part of Rajasthan, south, southeast and east of the Aravalli range receives more than 80 cm rainfall and has some important streams. The waterway Chambal is the biggest stream and is joined by certain feeders like the Banas, the Kali Sindh, and the Parbati. The stream Chambal is perpetual while its feeders may sporadically turn dry and show their stony beds. The stream Chambal starts from the northern sides of the Vindhyan scarps close to Manpur (884.4 m) in the south of Mhow runs for around 325 km through a long restricted and steep crevasse which overhangs the valley on both the sides ascending around 60 m to 90 m over the valley place.
