Universal Containers needs to ensure that its agent can immediately process customer returns by validating...

The correct answer is C because the requirement combines natural conversation with strict process sequencing. Agent Script procedural instructions are intended for exactly this hybrid pattern: the agent can still converse naturally, but mandatory steps such as order eligibility validation can be enforced before the return process continues. Option A is weak because Flow can execute validation logic, but “guiding the LLM” does not guarantee that the LLM will always follow the required sequence. Option B is excessive because moving the entire return process into Apex reduces configurability and is unnecessary when the main need is deterministic orchestration. Salesforce Agent Script guidance states that business-critical logic can execute reliably while conversational elements remain flexible, and run can execute required validations immediately when the code path is reached.
