Both the ans are correct, glass and filament are essential part of the bulb as filament is heated up it will glow + the glass helps to maintain vacuum Or gas in bulb.

I also think, its a filament as filament is more important part than glass. . As without glass, bulb glow but without filament with only glass bulb doesn't glow.

Bhai log we need current first because if the current is not there then it won't get light.

We have LED bulbs which neither have filament nor have glass. So all the options are wrong.

It's wrong to say that a bulb doesn't have glass. If it so then it's not bulb it is led.
It's not necessary to have a filament in bulb like CFL.

Common LEDs and LED light bulbs do not have a wire filament or any type of filament, because they produce light through a very different process than incandescent lights do.

Actually I fill D is correct but led lighting bulbs do not have a filament. That's why light is important for us. Mainly light is required for every people.
