Which term denotes the terminal node that represents the final prediction?

• A. Root
• B. Branch
• C. Node
• D. Leaf

Answer: (D)

In a decision tree, the final prediction is produced at the terminal node, which is called a leaf. After following the split criteria from the root through the internal decision nodes, you arrive at a leaf along each path. That leaf holds the predicted class label for classification or the predicted value for regression, and it has no further splits. The root is the starting point, interior nodes are where decisions occur, and branches are the connections representing the outcomes of those decisions. So the terminal node that represents the final prediction is a leaf.
