Explanation:

The main character in this story is "Montressor" because the story centers on him. As a primary character, Montressor can be found in the story's many different scenes. He is the protagonist in the story.

On the other hand, "Fortunato," is the secondary character because he acts as Montressor's victim. Secondary characters are essential in the story because their existence complete the story. Without Fortunato, Montressor will have no victim. As a victim, Fortunato will be sympathized by the readers but not that much admired just like the main character.
