Answer: 0.139
**Explanation:** The Information Ratio (IR) is calculated as: \[ IR = \frac{\text{Portfolio Return} - \text{Benchmark Return}}{\text{Tracking Error}} \] Given: - Portfolio Return = 13.2% - Benchmark Return = 12.3% - Tracking Error = 6.5% \[ IR = \frac{13.2\% - 12.3\%}{6.5\%} = \frac{0.9\%}{6.5\%} = 0.13846 \approx 0.139 \] Therefore, the correct answer is **0.139** (Option C).
