The ability to be stretched and drawn under stress into a wire is the definition of which property?

Explanation:
Ductility is the capacity of a material to undergo significant plastic deformation under tensile stress, allowing it to be drawn into or stretched into a wire. This quality is what makes metals like copper ideal for wiring—they can elongate considerably without cracking when pulled into thin strands. It’s different from malleability, which is about deforming under compressive forces to make sheets; toughness is about how much energy a material can absorb before fracturing, and conductivity is about how well it conducts electricity. So the ability to be stretched and drawn into a wire under stress is ductility.
