What type of game interaction commonly leads to illegal obstruction calls?

The correct response relates to how players interact with each other on the field. Illegal obstruction calls typically occur when a player intentionally or unintentionally prevents an opponent from moving freely to play the ball. This can occur when a player uses their body to shield the ball or blocks the path of an opponent without an attempt to play the ball, which falls under the rule of obstruction.

When considering the other options, player interference directly relates to obstruction, making it the most relevant choice. Out of bounds play does not involve interactions that would normally result in obstruction calls—it's a separate situation involving the ball leaving the field. Excessive force pertains to fouls or misconduct but does not specifically address the concept of obstruction, which is more about preventing movement rather than physical contact. Dual possession refers to scenarios where two players have simultaneous control of the ball, which also does not directly correlate with obstruction situations. Thus, the focus on player obstruction is crucial for understanding when and how these calls are made in soccer.
