What is the penalty for an incorrect or missing piece of uniform at a performance?

The penalty for an incorrect or missing piece of uniform at a performance is established to ensure that all members uphold the standards of discipline and presentation that are essential in a drill team setting. The reason this specific answer is correct is that issuing three demerits strikes a balance between accountability and encouragement for improvement. It reinforces the importance of uniformity and attention to detail while still allowing team members the opportunity to correct their mistakes in the future, rather than imposing a more severe punishment that could discourage participation or collaboration.

The option that states three demerits reflects a structured approach to maintaining uniformity, as the drill team likely values visual cohesion during performances, and having a strict penalty helps instill the seriousness of adhering to uniform standards among all members.
