Choose the correct part of speech for the highlighted word in each sentence.
The cat quickly jumped over the fence.

Correct option is A

The correct option is (a).

In the given sentence, the highlighted word quickly tells us how the action was performed. It modifies the verb jumped by showing the manner of jumping; therefore, it functions as an adverb.

Step-by-step reasoning:

• Identify the action (verb) in the sentence: jumped.
• Ask the question: How did the cat jump? The answer is quickly.
• Words that answer how/when/where/to what extent about a verb are adverbs.

Why other options are incorrect:

• Verb: A verb shows an action or state (jump, run, is). Quickly is not an action; it describes the action.
• Adjective: An adjective describes a noun/pronoun (quick cat). Here, quickly does not describe cat; it describes jumped.
• Noun: A noun names a person/place/thing/idea. Quickly is not a naming word.

So the correct answer is (a)
