To determine the correct usage of adjectives in this sentence, we need to understand how adjectives are typically used. Adjectives are used to describe or give more information about nouns. In this case, the noun being described is "monster."

The adjective "big" and the adjective "hairy" are both being used to describe the monster. To connect these two adjectives, we generally use a comma (,) to indicate the separation between them. So, in the correct option, the adjectives are written as "big, hairy."

Option 1, "big: hairy," uses a colon (:) instead of a comma, which is incorrect grammar.
Option 2, "big-hairy," uses a hyphen (-) instead of a comma, which is incorrect as the hyphen is typically used to combine two or more words into one.
Option 3, "big, hairy," uses a comma (,) to separate the two adjectives correctly.

Therefore, the correct sentence is: "Everyone in town ran away from the big, hairy monster."
