Final answer:
The removal of dialogue from 'The Cask of Amontillado' would primarily obscure Montresor's reasons for seeking revenge, affecting understanding of character motivations and the plot's development.
Step-by-step explanation:
The BEST description of how the text "The Cask of Amontillado" would be different if the dialogue were removed is that Montresor's reasons for seeking revenge would be obscured. Dialogue is crucial for providing insights into character motivations and actions. Without it, the intricacies of Montresor's vengeful plan, and the subtle psychological play between him and Fortunato, would be lost to the reader. The interactions between Montresor and Fortunato reveal the layered dynamics of their relationship and the progression of Montresor's scheme.
Answer choice (b) is partially correct; the arrogant nature of Fortunato would be less pronounced without dialogue but it's not as comprehensive in explaining the overall impact on the text. The setting (answer choice c) would still be conveyed through descriptive language, and Montresor's ploy (answer choice d) is largely revealed through his actions and internal monologue as well as dialogue.
