Answer:

O.

Step-by-step explanation:

  • The element which is oxidized is the element that losses electrons and its oxidation state be more positive.
  • The element which is reduced is the element that gain electrons and its oxidation state be more negative.

O goes from 0 to -2, so, it is the element that is reduced.
