Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
A xerophyte is a group of specific plants which have adapted to xeric habitats i.e., these plants occur in the soil which does not have sufficient amount of water. These plants have developed some specific structures such as thick cuticle, sunken stomata, waxy coating hairy surface for minimizing the process of transpiration which is the main source of water loss in the form of vapours in mesophytes. Hence option A is correct.
