What signal indicates a climber is ready to be lowered?

• A. The climber yells 'lower' and starts without confirmation.
• B. The belayer lowers without verifying readiness.
• C. The climber signals readiness and the belayer confirms with a controlled lowering.
• D. The climber ignores readiness and descends.

Answer: (C)

The signal relies on two-way communication and controlled action. The climber first indicates readiness to descend, and the belayer confirms by lowering in a controlled, steady manner. This ensures both are aligned: the climber is prepared, and the belayer is actively managing the rope to control the descent. Skipping verification or having the climber descend without confirmation can lead to sudden drops or rope issues, while simply ignoring readiness isn’t safe. The controlled lowering demonstrates that the belayer is ready, attentive, and maintaining proper rope control for a smooth, safe descent.
