To calculate the percentage of variation explained by the independent variables we need to use the coefficient of determination (R-squared), which is equal to (SST-SSE)/SST. 
In this case, R-squared = (102.55-82.04)/102.55 = 0.2 or 20.0%, which means that 20.0% of the variation in the dependent variable is explained by the independent variables in the regression. Therefore, the answer is A.
