The sacred groves called Orans are a feature of which state?

The correct answer is B, Rajasthan. An Oran is a patch of desert vegetation in western Rajasthan dedicated to a folk deity, made up of khejri, kair, jaal and rohida trees and the grass between them. It works as grove, village pasture and water point at the same time, and because it stays open scrub rather than closed forest, Oran land in Jaisalmer and Barmer is one of the last habitats of the Great Indian Bustard. Demands to record Orans as deemed forest come up repeatedly for this reason.

Option A is wrong because the Gujarat groves are usually simply called Dev or Devrai, the word shared with Maharashtra. Option C is wrong because Haryana has bani and bir patches but not Orans. Option D is wrong because the groves of Madhya Pradesh are local shrine forests without this name.
