Definition of Expert Systems:
An expert system is a type of artificial intelligence that uses knowledge-based reasoning to solve problems, make decisions, or emulate the processes of skilled human experts.
It consists of a knowledge base and an inference engine to analyze data and draw conclusions.
Applications of Expert Systems:
Used in fields like medicine (diagnostic systems), engineering, and finance for decision support.
Example: A medical expert system might suggest potential diagnoses based on patient symptoms.

B . Emulates the human brain: Refers to neural networks, not expert systems.
C . Longest stretch of activities: Refers to critical path in project management, unrelated to AI.
D . Knowledge-based system accomplishing tasks: Describes intelligent agents, not expert systems.
