Which of the following statements is TRUE concerning lifejackets?

Correct Answer: Option B — Lifejackets are designed to turn an unconscious person's face clear of the water.

SOLAS and 46 CFR requirements mandate that lifejackets be designed to provide sufficient buoyancy and stability to turn an unconscious person from a face-down position to a face-up position, ensuring the airway remains clear of the water surface. This is a fundamental performance standard for all approved PFDs.
