Select the choice which best identifies the given passage from "the cask of amontillado."

"putting on a mask of black silk, and drawing a roquelaire [cloak of knee length] closely about my person, i suffered him to hurry me to my palazzo [a large home or mansion]."

a: characterization
b: irony/sarcasm
c: setting
d: tragic resolution

I am pretty sure that the choice which best identifies the given passage from "The Cask of Amontillado."  is being revealed by the option A:Characterization. I consider this one to be correct because the rest of options are irrelevant to the topic and as you know characterization is a device which describes action objects, so it is correct.
