Which of the following is true about the kickoff that follows a goal in soccer?

After a goal is scored in soccer, the kickoff procedure is established by the Laws of the Game, which specifically outlines the requirements for how the game restarts following a goal. One key aspect is that players from the opposing team must be at least outside the center circle during the kickoff. This rule is important to ensure that the team taking the kickoff has space to execute the restart without immediate pressure from opponents, allowing for a fair play as the game continues.

It's important to note that the other options do not align with the established rules for a kickoff after a goal. For instance, the kickoff is not taken from the corner arc, rather it is taken from the center spot. Additionally, while players are positioned in their respective halves, it is not a requirement that all players must stay in their own half at the time of the kickoff; only the opponent's players must be outside the center circle. Lastly, the ball does not need to be rolling before play resumes, as it simply needs to be stationary for the kickoff to take place. The focus therefore is on the positioning of the opposing players in relation to the center circle.
