What must be present for youth lifters during their weigh-ins?

For youth lifters during their weigh-ins, it is essential for a parent to be present. This requirement ensures that there is adult supervision and support for the young athletes, which can be crucial in a competitive environment. The presence of a parent helps to create a sense of security and responsibility, ensuring that the youth lifter is adhering to the rules and regulations while also providing guidance and encouragement. This requirement reflects the importance of safeguarding youth participants in sporting events and promoting their well-being during the weigh-in process, which is a critical component of any competition.

The other choices, while they may involve different forms of support or oversight, do not fulfill the specific requirement of having a parent present, which is mandated for youth lifters. Having a peer lifter or a coach present may not provide the same level of responsibility or care that a parent would, and the option indicating that no one needs to be present does not align with the safety and support standards set for youth competitions.
