Which of the following is an example of a reach device?

The correct answer identifies a reach device as a paddle. In water rescue scenarios, reach devices are tools used to extend the rescuer's reach to assist a victim without placing themselves in danger. A paddle can be used to extend the distance the rescuer can reach to assist someone in the water. It allows the rescuer to maintain a safe distance while effectively maneuvering to offer aid.

Other tools listed, such as a throw bag, rescue frisbee, and life ring, serve different purposes. A throw bag is designed for throwable rescue where the rescuer throws a line to the victim instead of reaching out directly. The rescue frisbee is typically a tool intended for more playful or indirect rescue methods rather than direct reach. A life ring is a flotation device that can be thrown to a victim but does not aid in reaching them in the same way that a paddle can. Understanding the specific functions of each device helps distinguish their use in various rescue situations.
