Respuesta :
In this passage from "The Black Cat", by Edgar Allan Poe, what the reader can infer about the narrator from the businesslike tone of this passage is B. That he is without morals and possibly insane. The tone is the attitude the writer takes toward the subject. In this case, the businesslike tone when the narrator refers to the murder and the concealing of the body makes the reader feel that he has no regret for what he has done and so he can be a man without morals and probably insane.
