In the preparation of kids' drinks, why is a temperature of 100 F optimal?

A temperature of 100 F is considered optimal for kids' drinks primarily because it is safe for consumption. At this temperature, the risk of burns or discomfort from hot liquids is significantly reduced, making it a suitable option for children who may be more sensitive to temperature than adults. This consideration helps ensure that the drink can be enjoyed without risk, allowing kids to sip their beverages comfortably.

The other choices, while they may have some relevance in specific contexts, do not address the critical aspect of safety that is paramount when serving hot drinks to children. Comfort in consumption is essential, and maintaining a temperature that minimizes injury risk is a priority in kid-focused service.
