Question

Quizplus · Accepted Answer

The knowledge base stores all the information and rules needed to make decisions. The inference engine uses these rules to come up with answers to the questions asked by the user. The user interface allows users to interact with the system and ask it questions. Therefore, C is the correct answer since it includes all three main components of an expert system. A is incorrect because the workspace is not a major component of an expert system. B is incorrect because the explanation system is not a major component of an expert system, and the knowledge acquisition system is typically part of the expert system shell. D is incorrect because the knowledge acquisition system is separate from the expert system shell.
