• A. Compass
• B. Knife
• C. Whistle
• D. Flare

Answer: (C)

Signing for help is a fundamental safety function of a personal flotation device. An inflatable PFD is designed to keep you afloat and more visible, but you still need a quick, reliable way to attract attention. A whistle fits on the PFD, works without batteries, and can be blown to draw rescuers’ attention even in windy or rough conditions. A compass is for navigation, not signaling. A knife is a cutting tool, not a signaling device. A flare is a signaling device too, but it’s usually stored separately and used in specific situations, not as a standard attachment on the PFD. So the whistle is the practical, commonly provided signaling item on an inflatable PFD.
