Which of the following results from a player stepping out of bounds while dribbling?

When a player steps out of bounds while dribbling, the play results in a turnover. This means that the team that was in possession of the ball loses the right to continue play, and the opposing team gains possession. According to NFHS basketball rules, stepping out of bounds constitutes a violation that halts the play and leads to a change in possession. This rule is in place to ensure that both teams maintain fair play within the boundaries of the court.

The other options do not accurately represent the consequences of a player stepping out of bounds while dribbling. For instance, a warning is typically issued for minor infractions rather than specific boundary violations. Similarly, an automatic basket is not awarded for a player stepping out of bounds; points can only be scored through successful shots. Lastly, free throws are not awarded simply for stepping out of bounds; free throws are typically granted for fouls committed by the opposing team. Therefore, a turnover is the correct outcome in this scenario.
