The balanced half-reactions for this redox reaction are: Br₂(l) → Br⁻(aq) Br₂(l) + 2OH⁻(aq) → BrO₃⁻(aq) + H2O(l) By balancing the number of Br atoms and charge, we get the coefficients: Br₂(l) + 3OH⁻(aq) → BrO₃⁻(aq) + Br⁻(aq) + 2H2O(l) Therefore, the coefficients in front of Br₂ and OH⁻ are 3 and 3, respectively, which corresponds to choice D.
