In the question, "C₆H₁₂O₂" should be "C₆H₁₂O₆".

For the chemical equation :
C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + energy

C₆H₁₂O₆ is oxidized because the oxidation number of C increases from 0 (in C₆H₁₂O₆) to +4 (in CO₂).
OR: C₆H₁₂O₆ is oxidized because it accepts oxygen.

O₂ is reduced because the oxidation number of O decreases from 0 (in O₂) to -2 (in CO₂ and H₂O).
OR: O₂ is reduced because it donates oxygen.
