Which of the following statements about PFDs and Type IV devices is true?

Explanation:
PFDs are worn to provide buoyancy directly to the person, helping keep the wearer afloat and, for many types, keeping the face and airway oriented upward in the water. Type IV devices are throwable flotation aids kept on the boat to be tossed to someone in the water, not worn. They’re designed for rescue and require someone to grab onto them to benefit from buoyancy. So the statement that PFDs provide buoyancy to the wearer while Type IV devices are throwable flotation devices correctly captures how these two types of buoyant aids are intended to be used.
