Answer:
B. The narrator says he will die the following day
Explanation:
"But to-morrow I die, and to-day I would  unburden my soul. My immediate purpose is to place before  the world, plainly, succinctly, and without comment, a series  of mere household events. In their consequences, these events have terrified—have tortured—have destroyed me." This quotation from the story supports option B. The narrator makes it explicit that he will die the following day but before  his death, he wants to tell about his tortured soul. He has been suffering from a troubled soul.
