What are the common signs of drowning?

The correct choice identifies a common indicator of drowning, where the person may display flailing arms as they struggle in the water. This behavior often occurs as individuals attempt to keep their heads above water and make a desperate effort to stay afloat. It can be a sign that they are in distress and unable to swim to safety. Recognizing this flailing motion is critical for responders to initiate a rescue, as it differentiates a drowning individual from a swimmer who is simply swimming or playing in the water.

The other options depict scenarios that are typically not associated with drowning. A head tilted forward and mouth closed suggests a swimmer who is still managing their situation, while eyes remaining above the surface indicates that the person is not in immediate distress. A body lying still on the water's surface signals that the individual may already be unconscious or submerged, which presents a different kind of emergency response scenario. Understanding these distinctions helps rescuers assess the situation accurately and respond appropriately.
