What is the term for when a player steps out of bounds while playing?

The term "out of bounds violation" specifically refers to the scenario where a player steps out of the designated playing area during a game. According to the rules of basketball, when a player touches the ball or is holding the ball and steps on or over the boundary lines, the ball is considered out of bounds. Therefore, any play that occurs after this violation cannot continue, and the opposing team is awarded possession. This maintains the integrity of the court dimensions and ensures fair play.

The other terms listed do not directly describe this situation. For example, "out of play" may refer to situations where a ball is not in active play, but it does not specifically capture the nuances of stepping out of bounds. A "turnover" typically involves a team losing possession due to errors like traveling or stepping out of bounds, but it does not define the act itself. A "technical foul" relates to unsportsmanlike conduct or violations of game conduct, which is also unrelated to stepping out of bounds. Hence, the correct choice focuses precisely on the act of exiting the designated play area.
