What is common to the places known as Aliyar, Isapur and Kangsabati?

  1. A.Recently discovered uranium deposits
  2. B.Tropical rain forests
  3. C.Underground cave systems
  4. D.Water reservoirs

Correct answer

D. Water reservoirs

Explanation

The correct answer is D, Water reservoirs. Aliyar, Isapur and Kangsabati are all dams with reservoirs built for irrigation in different parts of India.

The Aliyar dam stands on the Aliyar river near Pollachi in Coimbatore district of Tamil Nadu, at the foot of the Anamalai hills, and is part of the Parambikulam-Aliyar project. The Isapur dam is on the Penganga river in Maharashtra, near the Yavatmal-Hingoli border, under the Upper Penganga project. The Kangsabati (Kansai) dam is at Mukutmanipur in Bankura district of West Bengal, one of the state's largest irrigation projects.

A is wrong because none of these places is known for uranium; India's main uranium mines are at Jaduguda in Jharkhand and Tummalapalle in Andhra Pradesh. B is wrong because these are dry or moist deciduous regions, not tropical rain forests. C is wrong because India's well-known caves, like Borra or Belum, are elsewhere.

Exam tip: Aliyar (Tamil Nadu), Isapur (Maharashtra), Kangsabati (West Bengal) are all reservoirs.
