Solution
The correct option is A 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 less reactive metal and is available in its free state.
