Answer: A. She is wealthy and upper class, but she is very unhappy.
Explanation: A paradox is statement or proposition which, despite sound reasoning from acceptable premises, leads to a conclusion that seems logically unacceptable or self-contradictory. In "The Great Gatsby" by F. Scott Fitzgerald, the character of Daisy represents a paradox, because she is wealthy and upper class (which one can think should make her happy) but she is very unhappy (which seems contradictory). So the correct answer is option A.
