Solution

The correct option is C it has high tensile strength
Pure tungsten has some amazing properties including the highest melting point (3695 K), lowest vapor pressure, and greatest tensile strength out of all the metals. Because of these properties, it is the most commonly used material for light bulb filaments.
Therefore option $C$ is correct.
