The Basketball centre line is part of the:

back court

The correct answer is Option (2) - back court

The basketball center line is part of the back court.

• The basketball court is divided into two halves by the center line.
• Once the ball crosses the center line from the back court towards the opponent's basket, it enters the front court.
• Since the center line itself isn't considered part of either the front court or the restricted area, it belongs to the back court.
