The correct answer is B because Agent Script is built for hybrid reasoning: flexible LLM-driven conversation plus deterministic procedural control. Declarative prompt text gives the model guidance and conversational flexibility, but it does not guarantee that steps happen in an exact order. Procedural instructions are used when business-critical logic must execute reliably, such as identity verification before a credit check. Salesforce's Agent Script fundamentals describe the - > arrow as the signal for procedural logic and explain that conditionals, running actions, and setting variables belong in that deterministic logic path. The same guidance distinguishes procedural logic from prompt text assembled for the LLM. Option A is wrong because procedural instructions can run actions that connect to Flows, Apex, or APIs. Option C is a tooling distraction, not a reasoning-pattern distinction.
