The aluminum carabiner is used on which of the following?

• A. Rope only
• B. Rope and can be attached to harnesses
• C. Cable only
• D. Harnesses only

Answer: (B)

Carabiners act as quick, secure connectors in rope and harness setups. An aluminum carabiner is chosen because it is strong yet lightweight, making it ideal for linking rope to protection or to a harness. In practice, you use the carabiner to clip the rope into the gear and to attach the rope or gear to your harness, enabling safe belaying, rappelling, and movement. That dual role—working with rope and connecting to a harness—explains why the best choice is rope and can be attached to harnesses. The other options don’t capture this versatile use: a carabiner isn’t limited to rope only or harnesses only, and “cable only” isn’t the typical task for most adventure activities.
