A redox reaction is a chemical reaction where electrons lost by one atom through oxidation are gained by another atom through reduction. An electron donor is a molecule that donates an electron to another molecule. This molecule, which gains electrons, is reduced while the molecule donating the molecule is oxidized. A reduced molecule cannot be an electron donor. Hence, the option (d) is incorrect.
