The iron content of foods can be determined by dissolving them in acid (forming Fe3+), reducing the iron(III) to iron(II), and titrating with cerium(IV):

 Fe2+(aq) + Ce4+(aq) → Fe3+(aq) + Ce3+(aq).

Identify the two half-reactions in the above reaction.
A) oxidation half-reaction   reduction half-reaction
Fe2+(aq) + e-→ Fe3+(aq)   Ce4+(aq) → Ce3+(aq) + e-

B) oxidation half-reaction   reduction half-reaction
Fe2+(aq) → Fe3+(aq) + e-   Ce4+(aq) + e- → Ce3+(aq)

C) oxidation half-reaction   reduction half-reaction
Ce4+(aq) + e- → Ce3+(aq)   Fe2+(aq) → Fe3+(aq) + e-

D) oxidation half-reaction   reduction half-reaction
Ce4+(aq) → Ce3+(aq) + e-   Fe2+(aq) + e- → Fe3+(aq)
