Electric Bulb Filament is made up of
Answer: C
The filament is made of tungsten.
An incandescent bulb gives light because its filament glows white-hot, at well over 2,000°C. Tungsten has the highest melting point of all metals, about 3,400°C, and evaporates slowly, so it can glow for a long time without melting.
Copper and aluminium are good conductors that would melt long before glowing brightly, which is why they are used in wiring. Lead has a very low melting point.
