Correct Answer :
A. A III, B IV, C I, D II
A - Cuticle: It is a protecting film covering the epidermis of leaves, young shoots and other aerial plant organs without periderm. It consists of lipid and hydrocarbon polymers impregnated with wax, and are synthesized exclusively by the epidermal cells.
B - Bulliform cells: They are large, bubble-shaped, empty colourless epidermal cells that occur in groups on the upper surface of the leaves of many grasses. Loss of turgor pressure in these cells causes leaves to roll up during water stress.
C - Stomata: They are minute aperture structures on plants found typically on the outer leaf skin layer, also known as the epidermis. They consist of two specialized cells, called guard cells that surround a tiny pore called a stoma.
D - Epidermis: It is the outer layer of tissue in a plant, except where it is replaced by periderm. It is a single-layered group of cells that covers plants' leaves, flowers, roots and stems. It forms a boundary between the plant and the external environment.
