How deep are the lane spaces on each side of the free-throw lane?

The correct answer is based on the specifications outlined in the NFHS basketball rules, which state that the lane spaces on each side of the free-throw lane measure 8 inches in depth. These lane spaces, also known as the "free-throw lane markings," are designed to help with player positioning during free-throw attempts, clearly defining the area where players are allowed to be before the ball is released.

Understanding the dimensions of the court markings is fundamental for players, coaches, and officials. This ensures proper execution of plays, adherence to rules, and maximizes fair competition during free throws. In contrast, other measurements such as 24 inches, 36 inches, or 12 inches do not correspond with NFHS guidelines for the free-throw lane and would imply a misunderstanding of court layout rules, potentially affecting gameplay strategies and player positioning during free throws.
