Detailed Solution

Thorn forests and scrubs receive less than 70 cm of rainfall. This type of vegetation is found in the northwestern part of the country. The northwestern region of the nation, which includes semi-arid regions of Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Uttar Pradesh, and Haryana, is home to this type of vegetation. The predominant plant species are acacias, palms, euphorbias, and cacti. Trees disperse throughout the landscape, with long roots that reach deep into the soil in search of moisture. Water is conserved as the stems are succulent. Leaves are generally thick and tiny to reduce evaporation. In drier locations, these woods give way to thorn forests and scrubs. Thorn forests and scrubs thrive in regions of the northwest part of India where the annual rainfall is less than 70 cm. So, the reason is the correct explanation of the assertion. Therefore both (A) and (R) are correct, but (R) is not the correct explanation of (A).
