Which setup uses a rules engine alongside a language model?
Why B is the answer
A hybrid flow, with rules for fixed logic
A hybrid flow combines an LLM with a rules engine. Fixed policy suits rules, and judgment suits the model.
In detail
- A hybrid flow uses rules for fixed logic and a model for language.
- Keep hard limits in the rules engine.
Use case
An illustrative scenario, not a real incident.
A loan flow uses rules for fixed limits and a language model to read free text. Fixed logic stays predictable.

Why the other options are wrong
- A. A second copy of the same system prompt, sent with every single request
