It very obviously belongs to B, anyone who thinks otherwise is a certified sociopath.
The real question we should ask is why the flute is currently in your possession anyway.
Why did you take it from girl B? Sounds like theft to me. And if you're her parent, she's gonna develop trust issues towards you and other people this way.
Give her the flute back and let her decide whether or not she wants to give it to either of the other girls.
