The answer is A – 1877. Edison managed to be the first person to invent a device that could record and playback sound. Others could record, but not playback.
Alexander Graham Bell perfected the basic Edison device and created the gramophone that we recognise today. However it was Emile Berliner that developed the flat disc, that we know as a record, rather than the cylinder used by Edison and Bell.
Good job, and thanks for the extra info, Mike!
