What confession does usher make to the narrator during the final storm?

When the narrator is terrified the Usher makes the confession that his sister was buried alive into the crypt and h did nothing to save her, but she was not dead but alive, the shrieking could be heard and the Usher kept repeating that he “darn not speak”. Even then he seems more concerned for himself.

answer: the first one

explanation:

explicitly is defined as “in a clear and detailed manner, leaving no room for confusion or doubt.” the rest are interpretive and not clearly proven leaving in fact possible “confusion or doubt” which explicitly, by definition cannot have.
