Answer:
The correct answer is option A, Cuticle
Explanation:
A plant leaf is covered by hydrophobic waxy layer known as cuticle that prevents the loss of water through the leaves. It acts as a barrier to the process of transpiration. It is made of cutin and lipids that are soluble in solvent and thus they are hydrophobic. Also cutin and lipid together form waxy covering over the epidermal layer of plant leaves which prevent any form of water exchange.
