Answer:
A. Cheerful, Bianca stayed outside happily
Explanation:
An adverb phrase is a group of words that usually refines the meaning of a verb, an adjective, or an adverb. Similar to adverbs, adverbial phrases modify other words by explaining why, how, where, or when an action occurred. We can see that in sentence A, that <u>the adverb is happily</u>, which is describing how Bianca stayed outside.
