Final answer:
Nick believes Gatsby might be disappointed with Daisy because the real Daisy cannot live up to Gatsby's idealized vision of her.
Step-by-step explanation:
Nick thinks that Gatsby may be disappointed with Daisy because Daisy could not possibly live up to the dreams that Gatsby had about her (C). Fitzgerald's narrative shows that Gatsby's idealized vision of Daisy does not align with reality, which is more complex and imperfect than his fantasies. Gatsby's dream of Daisy is also highlighted as something uniquely his; it does not represent a broader social or economic group but rather individuates Gatsby's singular experience, as indicated in the provided Fitzgerald passage. This sense of disappointment is woven through the narrative as Gatsby confronts the difference between his dream and the actual character of Daisy.
