Assertion : Xerophytic leaves may contain stomatal crypts or sunken stomata.
Reason : Spongy parenchyma is more in xerophytic leaves.

Options

A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false

Explanation

A sunken stomata is a stomata in a small pit which protects the escaping water vapor from air currents decreasing water doses from the leaf. Sunken stomata are commonly found in plants in arid environment as one of their adaptation to preserve water.
The spongy parenchyma is not found in xerophytes as it has many spaces between cells to facilitate the circulation of air and the exchange of gases.
