(N/A) The filament of an electric bulb is made of tungsten because it has a very high melting point (approximately $3380 ^\circ C$).
This high melting point allows the filament to become white-hot and emit light without melting when a large amount of heat is produced due to the flow of electric current.
Additionally, tungsten does not easily oxidize or react with air at high temperatures, which ensures the longevity of the bulb.
