(C) The reaction described is a disproportionation reaction,specifically the Cannizzaro reaction for aldehydes lacking $\alpha$-hydrogen atoms.$2HCHO + OH^- 	o CH_3OH + HCOO^-$In this reaction,one molecule of formaldehyde $(HCHO)$ is reduced to methanol $(CH_3OH)$ and another molecule is oxidized to formate $(HCOO^-)$.Therefore,formaldehyde undergoes self-oxidation and self-reduction.

Which of the following chemical substances undergoes self-oxidation and self-reduction during the same reaction?
