What role does personal flotation equipment play in preventing drowning?

Personal flotation equipment is designed primarily to provide buoyancy, which is critical in preventing drowning. When a person is in water, this equipment helps them stay afloat, reducing the risk of submersion and allowing for easier breathing. By keeping the head above water, it allows individuals to relax and conserve energy, making it easier to signal for help or swim to safety.

While personal flotation devices may offer some warmth in cold water, that is a secondary benefit and not their main function in drowning prevention. Jumping into the water safely is more about proper technique and not the role of flotation devices. Additionally, personal flotation equipment is not intended to enhance diving capabilities; its primary purpose is buoyancy and safety. Thus, option C accurately captures the essential function of personal flotation equipment in preventing drowning.
