stomata are sunken in pits

Detailed explanation-1: -Option C: In Xerophytes, as a part of special adaptation, sunken stomata are found, majorly on the lower surface of the leaf. Examples are Nerium, Pine, Acacia, etc. Therefore, this is the correct option.
Detailed explanation-2: -Xerophytes have sunken stomata to prevent water loss from the plant. They are often enclosed and partially covered by cuticles and are sunken within the leaf rather than on the surface. Plants with sunken stomata include Pine, Nerium, Acacia, etc.
Detailed explanation-3: -In the xerophytic plants, the sunken stomata are present. These stomata open during the night to prevent water loss. To adapt to this environment the xerophytic plant leaves reduce into spines, which reduces the surface area of the leaf and also reduces the amount of transpiration.
