Answer:
Choice A.
Step-by-step explanation:
Going over the options, you have to choose between
- credibility
- pomposity
- pomposity
- eventuality
We can rule out pomposity, because it is somewhat unrelated to the works of Edgar Allan Poe - his narrators are not often egocentric nor self-centered, so this word does not fit.
Eventuality is not a word used to describe an individual. It is a possible event or outcome, not something you would use to describe the narrators.
Credibility is the correct choice here. Many of Poe's narrators are mentally unstable, as seen in Cask of Amontillado or The Pit and the Pendulum. The reader does not have full unwavering faith in the narrator's telling of the events as they seem unrealistic or display the narrator's emotions dictating their actions.
