Answer: C is the best choice here.
But the choices are a bit oversimplified.
D could also be correct. The gramophone recorded on what we (who used them during the last part of the 20th century) called "records."
Explanation: Depending on where you get your information, you may get different explanations of the history of these recording devices.
Edison's original 1870 invention of a record player used a foil cylinder to record sounds. He later used wax cylinders. These are on display at the Henry Ford Museum in Dearborn, Michigan.
Around 1886, Emile Berliner began development of the Gramophone which used used flat discs for recording. The discs were originally made of shellac, later of vinyl. These are what became commonly known as records. Since the 1940's the gramophone has been called a record player, especially since electrical turntables and amplifiers replaces the earlier wind-up, spring driven turntables and mechanical-acoustical sound cones.
