Answer 2

The gases which are filled in the electric bulbs are b) Neon and argon

• The argon gas prevents the tungsten filament from getting flamed up. It helps the tungsten filament from decaying.
• If argon and neon were not present, then the air in the electric bulb would burn the tungsten.
• Hence, the corrosion of tungsten is saved by the addition of Neon and Argon.
