Read this excerpt from "The Tell-Tale Heart" by Edgar Allan Poe. His room was as black as pitch with the thick darkness, (for the shutters were close fastened, through fear of robbers,) and so I knew that he could not see the opening of the door, and I kept pushing it on steadily, steadily.

How does the situational irony of this excerpt affect "The Tell-Tale Heart"?

A )It makes the old man's death feel even more tragic because he never realized that the real danger to him was not from robbers outside, but from the man inside his home.

B)It shows that, despite what he says, the narrator was actually not very careful when he crept into the old man's room.

C)It makes the old man's death feel more deserved since he was clearly causing the narrator great strife by worrying so much about the danger posed to him by robbers.

D)It shows that, while the narrator is unreliable, he's actually telling the truth about the problems and pain that the old man caused.
