A reducing agent is a substance that donates electrons to another substance, thereby causing a reduction in the oxidation state of the recipient molecule. This is because oxidation involves the loss of electrons, so the donating of electrons by the reducing agent counteracts this process. Thus, choice B is the best answer as it describes the actual function of a reducing agent.
