Which of these offenses does NOT result in automatic dismissal from the match?

Unsporting behavior does not result in automatic dismissal from the match because it is generally considered a less severe infraction compared to the other offenses listed. Unsporting behavior typically results in a yellow card, which serves as a caution rather than an expulsion from the game. This can include actions like persistent fouling, arguing with the referee, or other actions deemed disrespectful but not violent or directly harmful.

In contrast, denying an obvious goal-scoring opportunity, violent conduct, and spitting are considered serious offenses that warrant a red card, leading to an automatic dismissal from the match. Denying a goal-scoring opportunity involves preventing an opponent from scoring in a clear situation, often through a foul. Violent conduct includes any physical action that is aggressive or harmful, while spitting is seen as a particularly disrespectful act and is automatically penalized with a dismissal as well.
