What statement about PFDs is true?

Wearing an appropriate Personal Flotation Device (PFD) significantly enhances a boater's safety on the water. Statistical data support that drownings are less likely to occur when individuals aboard a vessel are wearing PFDs, especially in emergencies. The effectiveness of PFDs in aiding buoyancy and providing essential support in water can make a critical difference, particularly in situations where individuals may find themselves unexpectedly in the water.

The other statements present misconceptions about PFDs. For example, not all PFDs automatically inflate; many types are inherently buoyant without the need for inflation. Furthermore, the requirement for PFDs applies to all individuals on board a vessel, not just children. Lastly, the notion that PFDs do not need to be worn in calm water is misleading, as accidents can happen under any conditions, reinforcing the importance of wearing PFDs at all times while boating.
