Show answer & explanation
Correct answer: A
The north-western part of Madhya Pradesh (the Gird/Chambal region – districts such as Bhind, Morena, Gwalior, Sheopur and Shivpuri) lies in the rain-shadow belt and receives comparatively low rainfall, giving it a semi-arid climate. So Reason (r) is true. Low rainfall and high evaporation in semi-arid areas support tropical thorn forests and scrub – stunted, open vegetation of acacia, prosopis, ber and other drought-resistant thorny species – so Assertion (a) is also true. The semi-arid climate is the direct cause of the thorny scrub vegetation, so Reason (r) correctly explains Assertion (a). Hence both are true and r is the correct explanation of a.
