Which of the following actions require only an attempt to be considered a foul?

Kicking or attempting to kick is classified as a foul because the act of kicking itself poses a risk of injury or unsportsmanlike conduct, regardless of whether contact is made with the opponent. The emphasis is on the intent and action of kicking, which represents a potential infringement on the rules of the game. Even if the attempt does not result in actual contact with the opponent, the action signals a level of aggression that can disrupt the flow of play and may endanger other players.

In this context, while "hold or attempt to hold" and the other options may involve actions that could be deemed inappropriate or outside the rules, they are not universally defined in the same way as kicking in terms of automatically being considered a foul based solely on the attempt. The rules prioritize the safety and respect among players, and kicking is a clear example of an action that must be carefully monitored, regardless of whether it results in successful contact or not.
