Answer: Ductility
Explanation: Copper is used in wiring because -
1. It is a metal which is a good conductor of heat and electricity due to the motion of the free electrons.
2. It has high ductility and malleability.
Ductility is the feature in which the metals can be stretched in to thin wires and Malleability is the feature n which the metals can be made into thin sheets.
3. These wires can withdraw a wide load of electric current.
