These materials exhibit both good strength and good ductility (formability) are option(a) i.e, metals.
The most malleable natural metals are gold, platinum, and silver, all of which can be stretched into fine wires and used for jewelry. Another extremely ductile metal that is frequently used in the electrical wire is copper.
The plastic deformation of metal that results from these kinds of strains is called ductility. The definition of "ductile" is a metal substance that can be stretched into a thin wire without weakening or becoming more brittle. Ductility is the quality of metals that allows them to be hammered thin or stretched into wire without breaking. It is a physical attribute of a metal that allows for the creation of thin wire.
