AnswerUPSC’s answer is (d).

Didwana, Kuchaman, Sargol and Khatu are saline lakes in Rajasthan, alongside Sambhar, Pachpadra and Lunkaransar. They lie in the arid and semi-arid west of the state, fed by seasonal streams, and have been important for salt production. They are not glaciers or mangroves. Remember: Rajasthan's inland saline lakes include Sambhar, Didwana, Kuchaman and Pachpadra.

Why each option is right or wrong
  • (a) Wrong: Rajasthan's arid plains have no glaciers.
  • (b) Wrong: mangroves grow in coastal tidal areas, not in Rajasthan's interior.
  • (c) Wrong: these four are known as saline lakes, not as Ramsar sites.
  • (d) Right: they are saline lakes of Rajasthan.

Answer: UPSC’s key. Explanation: written by UPSC Grade, not by UPSC.
