Solution

The correct option is C cuticle
Cuticle is a waxy coating present on the surface of the leaves. It is made up of cutin which is secreted by the epidermis of the leaf. A primary function of the waxy cuticle is to reduce water loss through the surface of the leaves, which is particularly important in water deficient areas like deserts which receives very little rainfall.
