Which expert system operating mode allows determining if a given hypothesis is valid?

Which expert system operating mode allows determining if a given hypothesis is valid?

A.
Blackboard

B.
Lateral chaining

C.
Forward chaining

D.
Backward chaining

Explanation:
Backward chaining (or backward reasoning) is an inference method that can be described as working backward
from the goal/hypothesis. It is used in automated theorem provers, inference engines, proof assistants and
other artificial intelligence applications.
Incorrect Answers:
A: A blackboard system is an artificial intelligence application based on the blackboard architectural model,
where a common knowledge base, the “blackboard”, is iteratively updated by a diverse group of specialist
knowledge sources, starting with a problem specification and ending with a solution.
B: Lateral chaining is not one of the expert system operating modes.
C: Forward chaining is the opposite of backward chaining. Forward chaining starts with the available data and
uses inference rules to extract more data until a goal (hypothesis) is reached.
