Answer:
A. Repetition of the word "I"
Step-by-step explanation:
In the story "The Black Cat" the narrator focuses on the urgency of the time. He has written the story before he was going to die. This urgency has been focused by the narrator by repeating the word 'I' and emphasizing on him. He had written the sentence just after he had cut the eyes of Pluto. The repetition focuses on his thought and sense of shame hidden in it. It helps in analyzing the tome of the narrator.
