Show answer & explanation

Correct answer: C

Answer: Forward chaining systems are data-driven, while backward chaining systems are goal-driven.

  • Forward chaining (data-driven): Starts with known facts and repeatedly applies inference rules to derive new facts until no more conclusions can be drawn. Common in production-rule systems and real-time data processing.

  • Backward chaining (goal-driven): Starts from a goal or query and works backward to find facts or premises that support that goal. Common in logic programming and goal-oriented problem solving.

Quick tip: If the reasoning begins from current data and moves forward, it is data-driven (forward chaining). If it begins from a desired goal and searches backward for supporting facts, it is goal-driven (backward chaining).
