D.)good conductor of electricity
Explanation:
One very important property of gold is that is a good conductor of heat and electricity.
All known metals are able to act as good conductors of electricity and heat due to the presence of a large pool of free mobile electrons in them.
Gold is a metal and it is not an exception. Like other metals, gold is not rigid but ductile.
It contains metallic bonds between its particles and is able to move electric currents.
