Answer 1

The question is asking to choose among the following choices that states the types of organic molecule  that is present to the kind of waxy coating in the said problem and base on my research, the answer would be Lipid, I hope you are satisfied with my answer and feel free to ask for more 

Answer 2

Answer;

-Lipid

Explanation;

-The plant cuticle consists of lipid and hydrocarbon polymers impregnated with wax, and is synthesized exclusively by the epidermal cells.

-The wax cuticle stops the water vapor escaping through the epidermis which is particularly important in arid deserts with little rainfall or Mediterranean climates with seasonal rainfall.

-A waxy layer known as the cuticle covers the leaves of all plant species. The cuticle reduces the rate of water loss from the leaf surface.
