Explanation:
Detailed explanation-1: -Disadvantages of decision trees They are not well-suited to continuous variables (i.e. variables which can have more than one value, or a spectrum of values). In predictive analysis, calculations can quickly grow cumbersome, especially when a decision path includes many chance variables.
Detailed explanation-2: -Expert-Verified Answer (B) The entropy of a node typically decreases as we go down a decision tree is true about a decision tree.
Detailed explanation-3: -Disadvantage: A small change in the data can cause a large change in the structure of the decision tree causing instability.
