Answer:
D. None of the choices are correct.
Step-by-step explanation:
In the short story "The Cask of Amontillado", by Edgar Allan Poe, the narrator is Montresor. From the very beginning, he makes it clear he wants revenge against Fortunato, but he does not explain why. Readers can make inferences, since Montresor uses the word "insult". However, anything can cause a person to feel insulted. It may have been something Fortunato said; it may have been something he did. It may have been business; it may have been love. We do not know, and the narrator does not care to tell. Therefore, the correct option is letter D. None of the choices are correct.
