8. Assuming a Classification and Regression Tree (CART) model is initially used to accomplish Step 3, as a further step which of the following techniques is most likely to result in more accurate predictions?

A. Discarding CART and using the predictions of a Support Vector Machine (SVM)

model instead.

B. Discarding CART and using the predictions of a K-Nearest Neighbor (KNN)

model instead.

C. Combining the predictions of the CART model with the predictions of other models – such as logistic regression, SVM, and KNN – via ensemble learning.
