Answer:
A. Crawled
Step-by-step explanation:
You are given the sentence:
The baby crawled slowly toward her favorite toy.
Your subject/direct object in this sentence, is the baby. Next you ask yourself, what is the baby doing? Crawling. This is your verb. The next thing to do, is recognize your adverb, which in this case, would be the word slowly. This would be a descriptive adverb, that many would mistake for an adjective, but looking into the sentence, we see that the adjective is the word, favorite, as it modifies the noun, toy. An adverb modifies a noun, a verb, an adjective, or another adverb. The word slowly in this sentence is modifying the verb crawled.
How did the baby crawl? Slowly.
