A.The narrator knows he will abandon Fortunato in the vaults.
Explanation:
The Barrel of Amontillado, by Edgar Alan Poe, is the narrative of the story of a man imbued with the desire for revenge and to think on the wall his dislike, Fortunato. In this excerpt, Fortunato is already trapped in the wall of the coffers and the narrator is amused by this situation, but intends to leave Fortunato there as part of the planned revenge.
The short story brings us to the realization that the protagonist will take revenge on a disaffection; in the middle, there are signs of what vengeance will be like; in the end, the protagonist exerts his revenge slowly. The reader follows the narrative doubting the outcome announced exactly because it is extremely simple and cruel and, in the end, line after line the protagonist simply delights listening to the last gasps of his disaffection.
Herea are the inferences to each of the excerpts: 1. The narrator has plotted his revenge in secret. 2. Luchesi does not know wines as well as Fortunato. 3. The narrator wants to convince Fortunato to leave the vaults. 4. Fortunato likes the Montresor family motto. 5. The narrator and Fortunato are worried about the late hour. I am pretty sure that the correct inference of the given passage from "The Cask of Amontillado" is the option : The narrator will make sure Fortunato is comfortable in the vaults. I consider this option as a correct one because Fortunato was killed by <span>Montrasor in this story. Do hope it will help!</span>
