But the question was A bulb always has so it also can be glass I mean both the ans can be valid.

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

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

Without the glass the bulb will not have its shape so glass will always be there.

Kumar said:   2 decades ago
Instead of Glass we can use even plastic.

So 'Filament' is the correct answer.

Vivek said:   2 decades ago
Some bulbs dont have glass, it is for safety purpose only but filament is must.

I think it should be D because LED does not have a filament.

It depends on the material you intend to use for the bulb.
