Selected Answer: B
In the context of linear regression, R² (coefficient of determination) measures the proportion of the variance in the dependent variable that can be explained by the independent variables in the model. Therefore, maximizing R² is the appropriate goal if you want the model that explains the most variation in the data. Hence, the correct answer is: B. R²
