Which option correctly states the PBE duration?

Explanation:
The question tests how long Protective Breathing Equipment (PBE) lasts in a smoke or fire scenario. A PBE provides a limited, breathable air supply to the wearer, just long enough to reach safety or complete an evacuation. The standard duration for crew PBEs is about 15 minutes, which is why 15 minutes is the correct choice. This duration reflects the typical time needed to move through smoke and to exits without the equipment becoming impractical in size and weight. Shorter times, like 10 minutes, could be insufficient for a full evacuation, while longer times, such as 25 or 35 minutes, aren’t the standard capacity for routine PBEs used in training and operations.
