Answer #1

Option d is correct

Explanation : Stomata are tiny pores found in the epidermis of leaves and other soft aerial parts. Stomata occur both on the upper and lower epidermal surfaces in mesophytic plants. Stomata are meant for gaseous exchange and are also the main source of transpiration.

So an adaptation for better gaseous exchange in plant leaves is stomata are present on the lower surface which are away from direct sunlight are very much effective for gases exchange.
