Answer:
The adverb in the sentence is:
B. really
Explanation:
"Long", "quiet" and "loud" are not adverbs - they are adjectives. An adjective is a word that modifies a noun or a pronoun by attributing a quality to it. In this case, "loud" is modifying "noise", "long" is modifying "break", and "quiet" is modifying "time".
On the other hand, an adverb is a word that modifies a verb, an adjective, or another adverb. "Really" is modifying the adjective "loud", intensifying it. Therefore, "really" is the correct option.
