What action should be taken if a player is found using bowls from two different sets?

When a player uses bowls from two different sets, it is crucial to address the situation promptly and appropriately to ensure fair play and adherence to the rules of the game. Advising the player that it is not permitted is essential because each set of bowls must comply with the regulations, which typically require all bowls to be from the same set to ensure consistency in performance and handling.

Using bowls from different sets can lead to discrepancies in weight, size, and material, which can provide an unfair advantage or disadvantage during play. This undermines the integrity of the game, as opponents are entitled to compete under the same conditions.

By informing the player that this practice is not allowed, you uphold the standards of the sport and ensure that all competitors are playing by the same rules. This action encourages compliance and strengthens the overall integrity of the competition. The other options do not adequately address the violation of the rules and could compromise the fairness of the game.
