What gives information about a verb?

The correct choice is an adverb because adverbs modify verbs by providing additional information about how, when, where, or to what extent an action is performed. For example, in the sentence "She ran quickly," the adverb "quickly" describes how she ran, giving us a clearer picture of the action.

Adjectives, on the other hand, modify nouns and provide information about a person, place, thing, or idea, rather than about verbs. Pronouns serve to replace nouns in sentences, helping to avoid repetition but not providing details about actions. Collective nouns refer to groups of individuals or things, which again do not give details about the actions themselves. Therefore, the role of an adverb as a modifier of verbs distinctly sets it apart from the other options.
