Correct Answer: Nitrogen


Solution : The correct option is Nitrogen .

Nitrogen is an inert gas that helps to reduce the degradation of the tungsten filament in incandescent bulbs by minimising oxidation. Nitrogen creates an environment inside the bulb that slows down the wear and tear on the filament, thereby extending the life of the bulb.
