The excess return is the difference between the total return of the portfolio and the total return of the index.

1. Calculate the Total Portfolio Return: $\text{Portfolio Return} = \sum (\text{Portfolio Weight} \times \text{Portfolio Sector Return})$ $= (0.20 \times 10.00\%) + (0.15 \times 15.00\%) + (0.20 \times 20.00\%) + (0.10 \times 8.00\%) + (0.20 \times 18.00\%) + (0.15 \times 15.00\%)$ $= 2.00\% + 2.25\% + 4.00\% + 0.80\% + 3.60\% + 2.25\% = 14.90\%`$2. **Calculate the Total Index Return:** $\text{Index Return} = \sum (\text{Index Weight} \times \text{Index Sector Return})$ $= (0.15 \times 12.00\%) + (0.10 \times 15.00\%) + (0.25 \times 22.00\%) + (0.05 \times 5.00\%) + (0.25 \times 10.00\%) + (0.20 \times 12.00\%)$ $= 1.80\% + 1.50\% + 5.50\% + 0.25\% + 2.50\% + 2.40\% = 13.95\%$3`. **Calculate the Excess Return:**$\text{Excess Return} = \text{Portfolio Return} - \text{Index Return} = 14.90% - 13.95% = 0.95%$.

The closest value is 0.95%, making Option C the correct answer.
