Answer: A) Simile.
Explanation: A simile is a figure of speech that consists in making a comparison between elements that aren't obviously related, this comparison is made using the words "like" and "as." In the given sentence, we can see an example of a simile that compares the way a girl ran to a cheetah chasing its prey (to give the idea that she ran very fast). The comparison is made using the word "like," so the correct answer is option A.
