 Once R5 gives 
ANY signal and catches the ball 
the play is over. 
Thus, it is not possible for K44 to "hit" R5 (after the catch and) while the ball is ALIVE!
Ruling for b) Invalid fair catch signal against R5, Dead Ball Personal Foul against K44.
Generally, R would want to keep the ball and thus 
both fouls would be enforced!
