The question says that R2 interfered with F6. At that point it's "Time! That's interference, runner is out. BR first." it makes no difference if he made the throw or not because at the point of interference the ball is dead. If they are saying there wasn't an actual interference then the play is as given. It's a bad question for the answer given. This is true in all codes.
