Verified Answer :

the answer is B, most adverbs are formed by adding LY to the end of the word , also an adverb is a word that describe and action and an adjective is the word that describes something.

Adjectives are the part of speech which qualifies the noun or pronoun. They may be placed before the qualifying word.

For example, this cute baby is eating an apple.

Whereas, adverbs refers to the set of words or word which qualifies the adjectives.

For example, the girls are speaking softly.

Hence, to form an adverb through adjective, they can be formed by adding –ly to the end of the word.

For example, they performed bad/badly in the exam

how did they perform? badly.

Hence, it is an adverb.
