The author of "The Black Cat" uses flashback to tell the story. Which passage from the story can only be used because of this structure?

A. In their consequences, these events have terrified have tortured have destroyed me.
B. Yet, mad am I not and very surely do I not dream.
C. Who has not, a hundred times, found himself committing a vile or silly action, for no other reason than because he knows he should not?
D. Hereafter, perhaps, some intellect may be found which will reduce my phantasm to the common–place . . .
