When can a player take a throw-in?

A throw-in can be taken when both feet are on the ground, and the ball is thrown from behind the head. This description aligns with the rules stipulated by the Laws of the Game governing throw-ins. When a player performs a throw-in, it is important that they maintain at least part of both feet on the ground and that the ball is released from behind the head to ensure the throw is legal.

The rules emphasize the necessity of proper technique during a throw-in to maintain the integrity of the game. Ensuring both feet are grounded provides stability and adherence to the rule that the throw must be taken correctly. The ball must also be thrown clearly from behind the head and released with both hands, demonstrating that the player is executing the throw-in properly. The player must also be facing the field of play upon executing the throw.

The other options do not appropriately reflect the regulations regarding throw-ins, which makes them incompatible with the accepted rules of soccer. Therefore, the correct answer emphasizes the fundamental requirements for successfully completing a throw-in.
