As a second probe to

• A. Complete the cycle
• B. Re-arm the weapon
• C. Disengage the circuit
• D. Engage the safety

Answer: (A)

The key idea is that delivering a second burst with a CEW requires a closed electrical loop. Completing the cycle re-establishes the current path so energy can flow again through the target via the second probe. Without finishing the cycle, the circuit stays open and no second pulse can be delivered. Re-arming, disengaging the circuit, or engaging the safety are related to readiness or stopping current, not enabling another discharge. So completing the cycle is the best answer.
