The whole sonnet is, in my opinion, about the fact that this woman does not love the poet - she is hiding her feelings well, and thinking about somebody else. So, the correct answer could be either C or D.
This is from Romeo and Juliette, Act 1 Scene 1. In this part of the
scene, Romeo explains to his cousin Benvolio that he's in love with a
girl named Rosaline, that she is beautiful and smart. However, he tells
Benvolio that she doesn't have the same feelings for him and that she's
sworn to live a life of chastity, which causes Romeo to "despair".
