I am trying to burn a CD came to a problem?

I am trying to burn a cd on itunes and yes I have done this before but this is the first time I have done it on itunes so I came to an option that I haven't had before. I am talking a cd I can play in a Cd player and in the car. After I click burn playlist to cd though an option comes up that says Audio Cd (if audio gap between songs), Mp3, or CD/Dvd? Which one do I choose for a cd to play in a cd player and in the car? I have tried choosing on my own before but now the cd wont even play so it appears I chose the wrong one which was cd/dvd. Which one is right please?
