• B. Leaf
• C. Root
• D. Branch

Answer: (D)

In a decision tree, the final predicted value or category is located at the leaf node—the terminal point where a path from the root ends. As you move from the root down, internal nodes split on features and you follow branches that correspond to those splits. When you reach a leaf, there are no further branches, and that leaf stores the prediction (a class label for classification or a numeric value for regression). The root is merely the starting point, internal nodes perform tests, and branches represent the outcomes of those tests. So the prediction lives at the leaf.
