What is an important fact about flotation devices?

The correct response highlights the importance of ensuring any flotation device is U.S. Coast Guard-approved. This is crucial because Coast Guard-approved devices have undergone rigorous testing to verify their safety and reliability. They are designed to provide adequate buoyancy and support in emergency situations, which enhances the safety of children when they are near or in the water.

Using non-approved devices could lead to potentially dangerous situations, as they might not provide sufficient buoyancy or protection in case of accidents. While other options touch on various aspects of flotation devices, the focus on approval by the Coast Guard is paramount for their effective and safe use in preventing drowning and ensuring child safety during aquatic activities.
