The answer to your question would either be b or c.
A metaphor compares two things without using the word LIKE or AS. The BEST answer would be (A) because the author is comparing her lips to blushing pilgrims, and she doesn't use the word like or as.
Hope this helps :)
If your looking for another word such as a synonym for who they include which,that one, the one in question, that fact, that other. <3
B/ Passive voice hope I am right
