I would go with B because most times when kids start to feel attracted to males/females, that happens while the teen is maturing.
Music has a very strange, psychological effect on people. Honestly, music is what keeps me trucking through school. But usually theres only a couple ways to get people to want to do something. One is Almost like mass hysteria, if you surround them with people who are excited to play the sport, and get them in a chant, they're going to get "pumped" to do it as well. To my knowledge, the other I wanted to cover, is music. If you've ever been on Spotify, you'll see they have "Work-out playlists." This is supposed to "hype you up" to power through the pain, just like if you wanted to relax you'd listen to classical, or orchestra music.
