My best guess would be, "B", "Grammatical conventions were much different then."
"The Black Cat" by Edgar Allan Poe has a theme of violence. Once again Poe uses the device of the unreliable narrator to weave a tale of horror and violence, stemming from the narrator's craven urge to destroy his family and pets. The theme in the story also develops as the protagonist.the moral the narrator learned was that violence against animals leads to bad things. the author develops the theme perfectly by blending the literary devices to create a story where the protagonist learns a valuable lesson.
