Answer:
D. Repetition of the phrase "hung it".
Step-by-step explanation:
Edgar Allen Poe's "The Black Cat" narrates the story of a man who killed not only his cat but his wife in his drunken state. His actions resulted in his death sentence which we came to know from the start of the story. He was to be hanged the following day.
With the repetitive use of the phrase "hung it", the author emphasized the importance of this phrase in the story. And as it will turn out, the narrator and protagonist will also be hanged for his crimes. The hanging of his cat is a foreshadowing of his own hanging that starts the story. The death of the cat, the re-imagining of the new cat as the dead cat all leads to the climax of the story. The "hung it" phrase played an important role in the plot, bringing the attention to this act in the forefront till the end.
