Alex is like pip in great expectations because he has such a natural sense of right and wrong. which type of rhetorical device is used in the sentence? a. epithet b. allusion c. eponym d. amplification

It would be letter B - allusion.

An allusion is a figure of speech that refers to a well-known story, event, person, or object in order to make a comparison in the readers' minds. In literature, it is an implied or indirect reference to a person, event, or thing or to a part of another text or story. There is an assumption that both author/speaker and reader/listener has knowledge on the topic, in this case, the Great Expectations, to understand the reference.

It's going to be the second option, or B.
