Answer
To identify which metal will produce the lowest theoretical potential when acting as an anode, we need to refer to the standard electrode potentials for the metals given in the options: Calcium, Copper, Iron, and Manganese. The more negative the standard electrode potential, the lower the potential for the cell when that metal acts as the anode.
