Solution
The correct option is A Monocot leaves
The guard cells which form the stomata are kidney or bean shaped in dicots but in monocots, the guard cells are dumb-bell shaped. In monocot leaves, stomata are equally distributed on both the surfaces. The leaves of monocots roll over to prevent excessive transpiration as rolling over reduces the surface area exposed to sunlight.
Thus, the correct answer is option A.
