NHSF - Player Control Foul Question

[routhless]

Since there is no such thing as a "loose ball foul"; what is the call for the following: Team B is in the bonus, Player A is dribbling with possession, looses the ball and commits a foul against Player B prior to Team B ever gaining possession? Is the call - a.) Player Control foul with Team B in-bounding or b.) Team B shooting foul shots (due to being in the Bonus)?

I'm just the scorekeeper, but the officials needed a discussion to resolve.
