Show answer & explanation
Correct answer: C
Expert systems are AI programs designed to emulate the decision-making ability of a human expert within a specific field. Statement I is correct because, unlike traditional software where the user initiates commands, expert systems often proactively provide recommendations or diagnoses to the user, directing the interaction flow. Statement II is also correct; expert systems are characterized by their narrow domain of expertise, focusing deeply on a specific area rather than possessing general intelligence. Statement III is incorrect because expert systems rely primarily on a knowledge base of rules and facts provided by human experts, rather than analyzing operational or external data dynamically like Business Intelligence systems. Therefore, only characteristics I and II accurately describe expert systems.
