Answer:
The correct answer is letter "C": Wagged.
Step-by-step explanation:
Adverbs modify adjectives, verbs and, other adverbs. In some cases, they can change the meaning of the words or in some others, they can add meaning. An effective way to spot an adverb within a sentence is to look for words ending in -ly. Besides, usually the adverb within that sentence answers a when, where or how question related to the word that is being affected. In our case:
* The curious puppy wagged its tail anxiously.
The word "anxiously" is the adverb modifying the verb "wagged", because it answers the question: How did the curious puppy wage its tail? -The answer would be: Anxiously.
