An oxidation-reduction -redox- reaction is a type of chemical reaction that involves a transfer of electrons between two species-xA0-Fe-Cu2-x21CC-Fe2-CuIn the above reaction- Fe is oxidised by gaining 2 electrons while Cu is reduced by loosing 2 electrons-Hence the above reaction is represents an oxidation-reduction reaction-Hence the required answer is -E-Fe-Cu2-x21CC-Fe2-Cu-
