D)Ramganga

Answer 1

Hint: 1)Baran is a district in Rajasthan and Baran town is the district headquarters.
2)There are 4 main major rivers which pass through Baran district.The Baran Rivers contribute to the Baran irrigation factor.

Complete answer:
Chambal is the main river which flows near the district baran.
The Chambal River, 1,024 kilometres (636 mi) long, originates from the Singar Chouri peak on the northern slopes of the Vindhyan escarpment near Mandav, 67.5 kilometres (41.9 mi) southwest of Mhow in Indore District, Madhya Pradesh state, at an altitude of about 843 metres (2,766 ft). The river flows first for about 376 kilometres (234 mi) in a northerly direction through Madhya Pradesh (M.P.) and then for 249 kilometres (155 mi) through Rajasthan in a generally north-easterly direction.

Lets see the options :
Luni : In north-western India, the Luni is the largest river in the Thar desert. It originates in the Aravalli Range valley of Pushkar, near Ajmer, passing through the southeast portion of the Thar Desert thus this option is wrong.
Chambal : Chambal river originates from singar chouri peak and passes near baran district thus this option is correct.
Kosi : A trans-boundary river that passes through Tibet, Nepal and India is the Kosi or Koshi thus this option is wrong too.
Ramganga : Ramganga is a Ganga River tributary that originates in the state of Uttarakhand, India thus this option is wrong too.

Hence, the correct answer is option (B)

Note: Much of the present-day Baran District was part of the Princely State of Kota before Indian independence in 1947. It was created by carving out the district of Kota on 10 April 1991.
The Chambal River is considered pollution-free[3] and hosts an impressive riverine faunal assemblage of 2 crocodilian species, the mugger and gharial.
