D

Answer to Question 2

In the best subset regression approach, sophisticated statistical software consider all of the possible combinations or subsets of the available predictor variables, then report which models are the best performers for each given number of predictors. Implicit in this process is the criterion by which one model is judged to perform better than another (e.g., coefficient of determination R2).
