Does "The Murders in the Rue Morgue" center primarily on how Madame L'Espanaye and her daughter were killed, on why they were killed, or on how C. Auguste Dupin solved the mystery surrounding their deaths?

The correct choice is C. The Crimes of Morgue Street is a novel that focuses on how Auguste Dupin solved the mystery surrounding their deaths.

Edgar Allan Poe as a good analytical and obsessive writer chooses the police genre to demonstrate his mastery in the execution of narrative plots. In this case, as in other stories such as The Golden Scarab, Poe teaches the reader the arduous process involved in solving mysteries.
