Playing and Stopping Audio

Hey there, I need some help figuring out how to play an audio clip for a multiple choice game. I want the music to start right off the bat, and when they get the question right, the music stops and a new clip begins to play. The game itself works, I just need to know how to play my audio clips. Thanks!
