Answer:
C. He is arrogant.
Step-by-step explanation:
Edgar Allen Poe's short story "The Cask of Amontillado," tells the story of how the narrator Montresor got his revenge on the insults he had endured at the hands of his friend Fortunato. And through careful planning and deceit, Montresor succeeded in luring Fortunato to his death.
Throughout the story, we see Montresor admitting that Fortunato is the culprit of his present 'avenging mind'. And even though Fortunato seemed unaware of what was happening, Montresor admits that "he was a man to be respected and even feared." But one thing is sure of Fortunato- that he is arrogant, especially in his knowledge of wines and the like. Fortunato "prided himself on his connoisseurship in wine", and insisted that "Luchresi cannot tell Amontillado from Sherry", thus seemingly emphasizing his expertise in the subject. And it was just how Montresor had planned to be, to play with his pride in wines and thus, follows the rest of the plot.
