If a decision tree is excessively tailored to its training data, which consequence is most likely if you prune it?

A)Increased training data overfitting
B)Reduced computational resource use
C)Decreased model generalization ability
D)Improved prediction on unseen data

💡 Explanation

Pruning reduces overfitting by simplifying the model and removing specific noise from the training data, because it reduces the model's complexity; therefore, pruning improves the model's ability to generalize to unseen data, rather than fitting the training data too closely.
