The correct answer is B) Life jackets are designed to turn an unconscious person's face clear of the water. This is correct because life jackets are required to have a design that will automatically turn an unconscious person's face up and out of the water, allowing them to breathe. This is a critical safety feature that helps prevent drowning. The other answer choices are incorrect: A) Life jackets do not need to be worn with the same side facing outwards, as they are designed to function properly regardless of orientation. C) Buoyant vests do not provide the same automatic face-up turning capability as life jackets and cannot be substituted in all situations. D) Discoloration or fading does not necessarily mean a life jacket will fail in the water, as long as it is properly maintained and in good working condition.
