Which of the following are types of rescue techniques in diving?

The selection that identifies "Surface rescue, in-water unconscious diver rescue, and responder assistance" as types of rescue techniques in diving is accurate because it encompasses a comprehensive range of scenarios that divers may face in emergencies.

Surface rescue refers to techniques employed when a diver is at the water's surface but is unable to assist themselves, requiring an immediate and effective response. In-water unconscious diver rescue is critical for situations where a diver goes unconscious underwater. This involves specialized techniques to safely retrieve the diver while ensuring the safety of both the rescuer and the victim. Responder assistance includes the coordination and help provided by other divers or rescue personnel, emphasizing the teamwork necessary in a rescue situation.

The other options do not fully capture the breadth of rescue techniques required in diving. While surface rescue and underwater navigation may involve safety skills, navigation is not a rescue technique. Relying solely on surface rescue methods overlooks crucial in-water scenarios. Lastly, basic swimming techniques, while essential for divers, do not specifically denote rescues or emergency responses. Therefore, understanding the comprehensive nature of rescue techniques is vital for effective diving safety and response.
