Answer: D) metaphor.
Explanation: a metaphor is a figure of speech that consists in making a direct comparison between elements that aren't obviously related, in order to create an image in the reader's mind. In the given excerpt we can see a clear example of a metaphor that compares a person's fancies to wasps buzzing among red apples. Notice that the speaker doesn't use the words "like" or "as" to make the comparison (therefore it isn't a simile).
