Having built a decision tree, we are using reduced error pruning to reduce the size of thetree. We select a node to collapse. For this particular node, on the left branch, there are 3training data points with the following outputs: 5, 7, 9.6 and for the right branch, there arefour training data points with the following outputs: 8.7, 9.8, 10.5, 11. What were the originalresponses for data points along the two branches (left & right respectively) and what is thenew response after collapsing the node?

• A. 10.8, 13.33, 14.48
• B. 10.8, 13.33, 12.06
• C. 7.2, 10, 8.8
• D. 7.2, 10, 8.6
