I think the best answer among the choices is the third option. The properties which make tungsten useful in the thin, glowing filaments of light bulbs are it has a high melting point and is electrically conductive. Its melting point is around 1650 degrees Celsius. Of all metals, it is the highest and also it does not melt even though it is glowing.

Answer:

Tungsten is ductile, has a high melting point, and is electrically conductive.

Explanation:

Metallic bonds are such that there is a free flowing electron cloud that is held by the metal cations. Tungsten can be easily beaten into fine wire making it a very ductile metal. The melting point of Tungsten is very high at 3422ºC. Tungsten does not melt even when it is at glowing temperature. Tungsten conducts electricity and glows.
