A decision tree model built with MinimumCasesForSplit=10, MinCasesAtLeaf=5, Pre-pruning=No, Pruning=Yes and maxDepth=10, exhibits overfit. To reduce overfit, you should:

I.

decrease MinimumCasesForSplit and MinCasesAtLeaf

II.

none of the choices will help reduce overfit

III.

decrease MinimumCasesForSplit and MinCasesAtLeaf

IV.

increase MinimumCasesForSplit and MinCasesAtLeaf

V.

decrease MinimumCasesForSplit, increase MinCasesAtLeaf
