When a ball rolls down a hill, what energy conversion occurs? O A. Kinetic energy to potential energy O B. Potantial energy to chemical energy O C. Potential energy to kinetic energy O D. Chemical energy to kinetic energy​

I'm not entirely sure about this one.
I found somewhere on the Internet that La parte mas importante del flamenco es el C. canto (the most important thing about flamenco is the song/singing), however, don't take my word for it.
I'm sorry, I hope you get it right. :/
