a. kinetic energy to potential energy to electric energy to sound energy
b. thermal energy to electric energy to kinetic energy to potential energy
c. chemical energy to electric energy to kinetic energy to sound energy
d. kinetic energy to electric energy to sound energy to potential energy

Explanation:

A battery stores chemical energy. When in use, it converts chemical energy to electric energy. The electric energy powers components that move (kinetic energy) to produce sound energy for the song.

Answer:

C. Chemical energy to electric energy to kinetic energy to sound energy
