(N/A) Tungsten is used for making the filament of an electric lamp because it has a very high melting point (approximately $3380 ^\circ C$), which allows it to glow at high temperatures without melting. Additionally, it has a high resistivity, which helps in generating sufficient heat when an electric current passes through it.
