Which statement accurately describes the inference engine?

• A. It generates user reports based on data
• B. It is responsible for rule selection and user interaction
• C. It serves as the main user interface for the expert system
• D. It contains all the data and structures of the database

Answer: (B)

The inference engine is a fundamental component of an expert system, as it is responsible for applying logical rules to the knowledge base to deduce new information or reach conclusions. Selecting the correct rules based on a user's queries or a specific scenario is a key function of the inference engine. It processes the inputs based on these rules, allowing the system to interact with users and provide them with relevant insights or solutions. This role sets the inference engine apart from other functions that don't focus directly on decision-making or logical reasoning, such as generating reports or serving as a user interface. While those aspects are important in broader system operations, the inference engine specifically deals with the reasoning processes necessary for the expert system to function effectively.
