A Fundamental Difference Between a Data Mining Approach to Problem

A fundamental difference between a data mining approach to problem solving and an expert systems approach is

A) the output of an expert system is a set of rules and the output of a data mining technique is a decision tree.
B) a data mining technique builds a model without the aid of a human expert.
C) a model built using a data mining technique can explain how decisions are made but an expert system cannot.
D) an expert system is built using inductive learning whereas a data mining model is built using one or several deductive techniques
