Helium gas is also used in bulbs except for nitrogen and argon because it is a noble gas. It does not react because its outermost shell is filled.

Nitrogen is the best option in normal bulbs. Because we can easily afford it easily. Argon can be also used to fill but it is costlier than N2.
Some lamps which are having color and fluoresces are having some metals with gas. Eg. NEON.

Hey guys, as per the options, Nitrogen is the answer here. But Argon is more suitable if it comes in options. The reason behind it is its more inert property than Nitrogen and this property can give longer life to the filament and in turn reduce the overall expense!:-).

Filament is made of nicrome and inert gas will not react with this. Filling a bulb with argon would be a costly process, whereas nitrogen is called inert as it does not react easily (78% nitrogen is present in our atmosphere).

Modern bulbs are usually filled with a mixture of argon and nitrogen. More rarely, some bulbs are filled with pure argon, krypton or xenon.
The earliest bulbs weren't filled with any gas, but had vacuum inside.

In automobile lamp H4 or HS bulb is used. Which I think is filled with helium gas. Anyone can explain more about it.

Bulbs are generally filled with nitrogen for commercial purpose, argon may also be used but it may be costlier.

Incandescent light bulbs are filled with an inert gas like nitrogen, argon, or krypton - So that the filament doesn't catch fire. Early ones were a vacuum.
