Solution:

A. Cuticle: It is a fatty substance( cutin) deposited over the surface of epidermal cells in the form of a separate layer. Usually, the cuticle is covered with wax which may be deposited in the form of granules, rods, crusts or viscous semi-liquid masses.
B. Bulliform cells: They are thin-walled and contain big vacuoles filled with water. They play an important role in folding and unfolding of leaves.
C. Stomata: A typical stoma is microscopic and usually consists of two kidney-shaped guard cells surrounding a pore.
D. Epidermis: The epidermis is single-layered (uniseriate) but in some cases, it may be more than one layer thick (multiseriate).
So, the correct option is A.
