They're both definitely unreliable, but the second answer(B) it doesn't seem like the narrator of "The Black Cat" seems insane, so I'm gonna think its D. I might be wrong though...
Answer: D. Both narrators appear to be irrational, which makes them both unreliable narrators.
In these excerpts, both narrators appear to be irrational. They are most likely mad, even though neither one of them admits to it. The first excerpt tells us that the narrator has enhanced senses, and that he can "hear many things in hell," which is an illogical thought. The second narrator claims that his senses reject their own evidence. This is simmilarly irrational. Therefore, we can conclude they are both unreliable narrators.
