D. A waxy coating on a plant

Explanation:

A cuticle can be described as a waxy covering which preserves or protects certain parts of plants like leaves, shoots etc. Lipid molecules which are saturated with waxes make up the cuticle. Cuticle majorly functions in stopping the evaporation of water from the cell's epidermal layers.  All the species of plants possess this waxy coating of cuticle because it plays important role in  stopping the loss of water from the cells.
