The correct answer is A because the requirement is immediate, deterministic sequencing after account creation. Procedural instructions in Agent Script are designed for multi-step workflows where the agent must run actions in a required order without waiting for another user turn. The specialist should structure the workflow so that after account creation succeeds, the procedural logic runs the verification email step before advancing to profile setup. Option B is weaker because making an action available does not force immediate execution. Option C is phrased incorrectly because run belongs in Agent Script procedural instructions, not inside the create account action itself. Salesforce Agent Script recipes describe action chaining with run, step tracking, procedural instructions, and automatic follow-up action execution in multi-step workflows.
