Which phrase completes the rappel command sequence: 'on belay, belay on, on rappel, ?'

• A. Rappel on
• B. On belay
• C. Belay on
• D. On rappel

Answer: (A)

Clear, unambiguous communication between climber and belayer is essential during rope work to keep everyone safe and aligned on what’s happening. In this sequence the climber signals readiness to descend with a phrase that states they are on rappel. The belayer then gives a distinct go-ahead by saying “Rappel on,” which authorizes the descent and keeps the action explicit and coordinated. That go-ahead is the natural next step after the climber confirms readiness, because it shifts from stating the status to allowing the action to proceed. The other options either reiterate belay status or reflect readiness from the wrong side of the action, so they don’t serve as the proper cue to start the rappel.
