Universal Containers is designing an agent to assist with order management and dealer support automation.

The correct answer is C. The team already has the variable and plans to use a guard condition, but the guard is useless unless the variable is updated after the verification action succeeds. @utils.setVariables or equivalent variable-setting logic must change is_verified to true when the dealer passes verification. Option A is incomplete because adding the guard only defines the condition; it does not change the state that the condition evaluates. Option B is wrong because an immutable variable would prevent the verification status from being updated during the session. In Agent Script, variables maintain state across turns and subagents, and filters or availability rules use that state to control what the reasoning engine can access.
