Answer: The correct answer is b. metaphor.
Explanation: A metaphor is a figure of speech that compares two things by stating that one thing is another thing, without using "like" or "as." In the given sentence, "Michel was flying like an eagle," the comparison is made between Michel and an eagle. This comparison suggests that Michel was soaring gracefully and effortlessly, just like an eagle does when it flies.
In contrast, a simile uses "like" or "as" to make a comparison. For example, if the sentence said "Michel was flying like an eagle," it would be a simile. But in this case, there is no direct comparison using "like" or "as," so it is a metaphor.
Antithesis, on the other hand, is a rhetorical device that involves contrasting or contrasting ideas or words within a sentence or paragraph. It is not applicable in this sentence because there is no contrasting idea or word being used.
To summarize, the sentence "Michel was flying like an eagle" is an example of a metaphor because it compares Michel to an eagle without using "like" or "as."
