D Correct answer
Explanation

Epidermis is in two layers, one on each surface of the leaf. Both the epidermal layers are composed of compactly arranged, barrel shaped cells. Cuticle and trichomes are present in both the layers. Stomata are found in both the epidermal layers. This condition is described as amphistomatic. A few cells in the upper epidermis are enlarged to form motor cells called bulliform cells.
