When can a player be cautioned for unsporting behavior?

A player can be cautioned for unsporting behavior for a variety of actions that are considered unfair play. This encompasses behaviors that go against the spirit of the game, such as simulation (diving), delaying the restart of play, or engaging in excessive celebration after scoring a goal. It's important to note that unsporting behavior is not restricted to specific moments or only to verbal disputes with officials; rather, it is applicable throughout the match whenever a player displays such actions.

While other options may mention situations that can lead to cautioning, they lack the broader criteria that defines unsporting behavior. Actions constituting unsporting behavior can occur in numerous circumstances, making them a key aspect of maintaining fair play during the match.
