Answer : The correct answer is : Ruling: Legal in (a) and (b). Illegal in (c) as the controlled toss of the ball to the court by A1 constituted the start of a dribble, dribbling a second time after picking up the ball is an illegal dribble violation. In basketball, an illegal dribble occurs when a player finishes his dribble by catching or having the ball rest in one or both hands and then bounces it with one hand or when a player touches it twice before the ball touches soil.
