Final answer:
Option B). The irony in the narrator's method of disposing of the body in "The Black Cat" is that the attempt to cleverly conceal the crime is ultimately what exposes it.
Step-by-step explanation:
The irony of the narrator's technique of disposing of the body in Edgar Allan Poe's "The Black Cat" is what makes it significant. The narrator, believing he has cleverly covered up his crime, walls up the body in his home's basement. However, this alleged cunning is paradoxically called into question when the cops find the corpse after hearing the mewling of the accidentally caught cat. What was intended to be the ideal hiding place—the wall—becomes the very symbol of his guilt. Poe frequently explores this issue in his writing, showing how a character's arrogance and cunning ultimately bring them to ruin.
