A certain voltaic cell has a cell potential of +1.60 V works on an overall reaction of AuBr₄^–(aq) + Cr(s) → Au(s) + 4 Br^–(aq) + Cr³⁺(aq). Provide the two half-cell reactions involved. 

• A. Oxidation half-reaction: Cr(s) + 3 e^– → Cr³⁺(aq)
  Reduction half-reaction: AuBr₄^–(aq) + 3 e^– → Au(s) + 4 Br^–(aq)
• B. Oxidation half-reaction: Cr(s) → Cr³⁺(aq) + 3 e^–
  Reduction half-reaction: AuBr₄^–(aq) + 3 e^– → Au(s) + 4 Br^–(aq)
• C. Oxidation half-reaction: AuBr₄^–(aq) → Au(s) + 4 Br^–(aq) + 3 e^–
  Reduction half-reaction: Cr(s) → Cr³⁺(aq) + 3 e^–
• D. Oxidation half-reaction: AuBr₄^–(aq) + 3 e^– → Au(s) + 4 Br^–(aq)
  Reduction half-reaction: Cr(s) + 3 e^– → Cr³⁺(aq)
