The given equation depicts the reaction:
\[ \text{Au}^{3+} + 3e^- \rightarrow \text{Au} \]
In this reaction, gold ions (\( \text{Au}^{3+} \)) gain electrons (\( 3e^- \)) to form neutral gold (Au). Since the process involves the gain of electrons, it is a reduction reaction.
Therefore, the correct answer is:
**B. reduction**
