What does ductility of metals mean?

Correct answer: Drawn into wires

Direct answer: Option B, drawn into wires. Ductility is the property of a material that allows it to be stretched or pulled into thin wires without breaking. Metals often show this property because their particles can shift while the metallic bonding remains effective. Step by step: apply a pulling force to a metal; if it can become a long, thin wire instead of snapping, it is ductile. Copper and aluminium are familiar examples used for electrical wires. Option A, beaten into sheets, describes malleability, not ductility. Malleability is the ability to be hammered or pressed into thin sheets. Option B is correct because “wire” is the key word in the definition of ductility. Option C, dissolving in water, is solubility, which is a different property and is not the meaning of ductility. Option D, changing into gas, is vaporisation or conversion to a gaseous state, usually by heating, and is unrelated to mechanical shaping. Do not confuse ductility with malleability: ductility is tested by pulling into wire, while malleability is tested by hammering into sheets. Memory cue: “Ductility—drawn into wire; malleability—made into a sheet.”
