Hint: Here, we will proceed by defining the element inside a blub and the fact that it should be coiled. The element is tungsten. Then, we will mention the important properties of this element and due to those properties we will specify the use of this element.

Is the symbol for an electric bulb.

Hence the correct option is A.

Additional Information:
Tungsten (W) is also called wolfram. It is a chemical element which is an exceptionally strong refractory metal of Group 6 of the periodic table which is used in steels to increase the hardness and the strength and in lamp filaments.
Tungsten is known to be one of the toughest things found in nature. Its melting is almost impossible and they are super dense. Pure tungsten is a silver-white metal, which can be combustible and can ignite spontaneously when made into fine powder. Natural tungsten has five stable isotopes and an additional 21 unstable isotopes.
Tungsten is used in a variety of ways since it is very strong and durable. This is very corrosion resistant and has the highest melting point and maximum tensile strength of any element. However, its strength comes when it is transformed into compounds. Pure tungsten is too soft. Due to its high melting point, tungsten is used in the manufacture of the electric bulbs.

Tungsten has the highest melting point of all metals, and alloyed to reinforce them with other metals. Tungsten and its alloys are used in many applications of high temperatures, such as arc-welding electrodes and heating elements in high temperature furnaces. Tungsten carbide is incredibly hard and very important for the metalworking, mining and petroleum industries.
