The two sentences that use coordinate adjectives are "The dark, musty cellar..." and "The dark-haired, hazel-eyed baby...", options A and C as explained below.

<h3>What are coordinate adjectives?</h3>

First, we must remember that adjectives are words that modify nouns by giving them a quality. Examples of adjectives are:

Beautiful

Smart

Silly

Coordinate adjectives are adjectives that have the same importance in the sentence and that modify the same noun. They appear in a row and are separated by a comma. Since they have the same importance, their places can be swapped without harming the meaning of the sentence.

That is the case with options A and C. There is a comma separating the adjectives "dark" and "musty" in letter A, and "dark-haired" and "hazel-eyed" in letter C. In both cases, the adjectives can be swapped without any problems.
