The primary function of a sectional view is to reveal:.

c) Interior features

Explanation:

Imagine you draw a machine. What people can see in your drawing is the outside of the machine, how it looks externally. If you wish to show people what the machine looks like on the inside, you will need to draw a sectional view of it. It's as if you are drawing the machine with part of it cut open, as if a section of it has been removed.

Another example I could give you is when Medicine and Biology students study anatomy. Since they need to see what bodies look like on the inside, they often work with sectional view drawings of body parts.

there are no options provided but you can choose among the following gender-neutral pronouns: zir, hir, eir, vis, tem, eir.

in the normal course of maintaining a pronoun-antecedent agreement, we could have used the words his or her but since we are also required to use gender-neutral language, we need to replace it with its equivalent gender-neutral pronoun.
