Solution

The correct option is D Calcium
Calcium is a highly reactive metal. It can lose its electrons easily to form cations. Hence it can be extracted by electrolysis of its molten chloride salt.

Zinc and copper are moderately reactive metals. These metals can be extracted by calcination or roasting.

Gold is a metal which has a very low reactivity and is available in its free state.
