Solution

The correct option is C It is a good conductor of heat and electricity
Copper has the best electrical conductivity of any metal, except silver. Current flows easily through copper thanks to its small electrical resistance, without much loss of energy. This is why copper wires are used in mains cables in houses and underground. Copper is a good conductor of heat and is used in many heating applications as it doesn't corrode and has a high melting point.
