Which option accurately reflects a function of life-saving devices?

• A. They decorate the vessel.
• B. They provide means of escape, flotation, and rescue during emergencies.
• C. They measure wind speed.
• D. They control ballast water.

Answer: (B)

Life-saving devices are meant to save lives in emergencies by providing escape routes, flotation, and a way for rescuers to reach those in need. That purpose is exactly what this option describes, since life jackets, lifeboats, liferafts, and related gear keep people afloat and enable safe evacuation and rescue. The other choices don’t fit because decorative items don’t enhance safety, wind speed is measured with instruments like anemometers, and ballast water control deals with ship stability and cargo management rather than immediate life-saving during an emergency.
