• A. Remain seated with seat belts fastened.
• B. Stand and move about the cabin.
• C. Unbuckle belts during turbulence.
• D. Ignore the sign until it is off.

Answer: (A)

When the fasten seat belt sign is on, the priority is to keep passengers safely restrained during times when the aircraft could experience sudden motion. Keeping your seat belt fastened reduces the risk of injury from unexpected turbulence or abrupt maneuvers and helps crew move about the cabin or evacuate if needed. Standing or walking during this period can lead to falls or being struck by objects, and unbuckling defeats the purpose of the warning. Ignoring the sign isn’t safe because it’s a clear instruction from the crew about when extra precautions are required. Stay seated with your belt fastened until the sign is turned off or the crew tells you it’s okay to move about again.
