Which outcome occurs when a decision tree, used for image classification, splits nodes based solely on maximizing information gain without any pruning?

A)Reduced model interpretability occurs
B)Underfitting of training data appears
C)Improved generalization on unseen data
D)Overfitting to training data develops

💡 Explanation

Overfitting develops because the decision tree excessively learns noise from the training set through the Information Gain mechanism without regularization from pruning; therefore, the tree fits the training data too closely, rather than generalizing to new data like pruning would allow.
