What is a defining characteristic of rule-based AI?

• A. It relies on deterministic logic rather than learning from data.
• B. It learns from labeled data to make predictions.
• C. It primarily generates new content.
• D. It relies on probabilistic modeling.

Answer: (A)

Rule-based AI operates by explicit, human-written rules—if-then statements—that drive decisions through deterministic logic. Because the behavior is encoded in these fixed rules, the same input always produces the same output, and there isn’t a training process that updates the system from data. This contrasts with learning-based approaches that derive patterns from labeled data and adjust their internal models accordingly. The other options describe learning, generative capabilities, or probabilistic methods, which aren’t the defining feature of a rule-based system.
