Answer: D. adjectives that appear together to describe the same noun
Step-by-step explanation:
Adjectives are words that describe or provide additional information about a noun. Coordinate adjectives are two or more adjectives that are used together to describe the same noun. They are always separated either by the word 'and' or with comma. Some examples are:
John lives in a large, expensive house.
His daughter is a smart, hard-working woman.
It is going to be a successful and profitable year.
