Respuesta :
The correct answer is D.
The narrator, Montresor, has disguised himself in order to get revenge on Fortunado for having insulted him.
Knowing Fortunato's love for wine, he offers him to try something that could pass for Amontillado. Fortunato agrees to go with him to his vault to try the sherry. However, the vaults are covered with nitre, which start poisoning Fortunato.
When Monstresor sees him coughing he offers to go back, and says that he will give the sherry to Luchesi, Fortunato's enemy. This convinces Fortunato to stay, since he does not want his nemesis to try the sherry and he does not know the narrator is trying to kill him.
