**Redox Reaction Balancing**

In this exercise, we aim to balance the following redox reaction, which occurs in a basic solution:

\[ \text{Br}^- + \text{CrO}_4^{2-} \rightarrow \text{BrO}_3^- + \text{Cr(OH)}_3 (s) \]

**Question:** When this reaction is correctly balanced, what is the coefficient in front of \(\text{CrO}_4^{2-}\)?

**Options:**

- 2
- 3
- 1
- 10
- 6

To solve this, apply techniques from redox balancing, ensuring that both the mass and charge are balanced in the equation. Consider the oxidation states, electron transfer, and stoichiometry in a basic solution.
