What Is the Reduction Half Reaction for the Following Chemical

Multiple Choice

What is the reduction half reaction for the following chemical reaction in a basic solution? ClO^-(aq) + Cr(OH) ₄^-(aq) → CrO₄^2-(aq) + Cl^-(aq)

A) ClO^-(aq) + 2 H⁺(aq) + 2e^- → Cl^-(aq) + H₂O(l)
B) ClO^-(aq) + H₂O(l) + 2e^- → Cl^-(aq) + 2 OH^-(aq)
C) Cr(OH) ₄^-(aq) + 4 OH^-(aq) → CrO₄^2-(aq) + 4 H₂O(l) + 3e^-
D) Cr(OH) ₄^-(aq) → CrO₄^2-(aq) + 4 H⁺(aq) + 3e^-
