Detailed Solution

Concept: The tendency of metals to be drawn out into wire or threads or to be pounded out thin is known as the ductile behaviour of metal. They are capable of changing their shape without breaking.
When tensile stress is applied, a material's capacity to thinly stretch is referred to as its ductility. One typical kind of ductile material is solid metals that do not shatter when pounded. Some examples of ductile metals include steel, copper, and aluminium.
Most metals are ductile by nature, which allows for the formation of long, thin structures like electric wires made of aluminium. Even while the majority of metals exhibit ductility, some metals do not. For instance, zinc is brittle, not ductile or malleable, and mercury cannot be deformed into wires since it is the only metal that is liquid. Additionally, it is challenging to distort sodium and potassium into wires.
Hence, the correct answer is option 2.
