Which of the following excerpts from the short story “The Tell-Tale Heart” by Edgar Allan Poe best demonstrates the unreliability of the narrator? A.
You should have seen how wisely I proceeded—with what caution—with what foresight—with what dissimulation I went to work!
B.
I heard many things in hell. How, then, am I mad? Hearken! and observe how healthily—how calmly I can tell you the whole story.
C.
And then, when I had made an opening sufficient for my head, I put in a dark lantern, all closed, closed, that no light shone out, and then I thrust in my head.
D.
Oh, you would have laughed to see how cunningly I thrust it in! I moved it slowly—very, very slowly, so that I might not disturb the old man's sleep.

the answer is:

B) I heard many things in hell. How, then, am I mad? Hearken! and observe how healthily—how calmly I can tell you the whole story.

He asks the reader how they could think him mad. This shows that he is unreliable because he says something, but then contradicts it through his actions.
