Which statement identifies a belay cable's backup?

• A. Bright color
• B. It has a full strength back up
• C. Tag reads 'Cable'
• D. It has a flashing label

Answer: (B)

A belay cable needs a backup that can carry the same load if the primary line fails, providing true redundancy for safety. Describing the backup as full-strength means it’s capable of taking the full load just like the main line, which is essential to prevent a fall if the primary line drops or breaks. The other options focus on visibility or identification rather than actual safety function: a bright color helps you see the line, a tag that reads “Cable” identifies it, and a flashing label might warn or draw attention, but none of these ensure the backup can carry the load. Therefore, identifying the backup as full-strength best captures how a belay system maintains safety.
