Solution

The correct option is D Tungsten
A filament is made up of a metal having a high melting point because a bulb lights up only by heating the filament. The heated filament is the source of light, and if the melting point of the filament's metal is low, it may melt.
Copper, aluminium, and lead are not used as filament metal since they have a relatively low melting point.
Hence, Tungsten metal is selected for making filaments of electric bulbs as tungsten can sustain high temperature and has a high melting point.
