Best answer
Correct choice is (d) Tungsten

For explanation I would say: The melting point of Tungsten (W) is very high (3422°C). It has the highest melting point among all the metals. This property of Tungsten makes it excellent for use as filaments in light bulbs as it can resist high temperatures.
