The correct answer is D.

Explanation:
Copper can be extracted from its ore by heating it with carbon. Impure copper is purified by electrolysis in which the anode is impure copper, the cathode is pure copper and the electrolyte is copper sulphate solution. An alloy is a mixture of two elements, one of which is a metal.

D ans is Sn,from cassiterite,the rest is extracted by reduction

There is no option for this becausÉ cu is least reactive,fe and sn are moderately reactive Ąπϑ only metals they a very reactive like aluminium can be obtained from electryotic reduction
