What happens if the ball enters the goal from a throw-in?

When the ball enters the goal directly from a throw-in, the correct outcome is to restart the game with a goal kick for the opposing team. This is in accordance with the Laws of the Game, specifically Law 15, which states that a goal cannot be scored directly from a throw-in. If there is an attempt to score from a throw-in, regardless of whether the ball successfully enters the goal or not, the play is considered invalid, and the opposing team is awarded a goal kick. This reinforces the idea that throw-ins are intended to reintroduce the ball into play rather than serve as a method of scoring.

In summary, when analyzing the other choices, it can be clarified that a goal is not awarded to the opposing team, the throw-in cannot be considered valid if it results in a goal, and there's no process for reviewing a throw-in goal since it is fundamentally not allowed in the game's rules.
