A Correct answer
Explanation

An airplane should NEVER be refueled inside a hangar. This is a strict safety rule because hangars are enclosed spaces with poor ventilation, and fuel vapors can accumulate creating a severe fire/explosion hazard. Refueling must be done outdoors or in designated well-ventilated areas away from enclosed structures. The time of day or presence of pilots does not change this fundamental safety prohibition.
