[tex]oxidation \: number \: of \: oxygen = \\ before \: rxn = - 2 \\ after \: rxn = - 2[/tex]

[tex]oxidation \: number \: of \: hydrogen = \\ before \: rxn = + 1 \\ after \: rxn = \\ 2x - 2 = 0 \\ x = + 1[/tex]

[tex]oxidation \: number \: of \: carbon = \\ before \: rxn = \\ x - 6 = - 2 \\ x = 4 \\ after \: rxn = \\ x - 4 = 0 \\ x = 4[/tex]

Option A

[tex]oxidation \: numbers \: remain \: constant \\ so \: none \:a re \: undergoing \: oxidation \: \\ nor \: reduction \: [/tex]
