Name a common knot used for rope-assisted self-rescue or ascent.

• A. Slipknot.
• B. Bowline.
• C. Prusik knot.
• D. Figure-eight on a bight.

Answer: (C)

A knot used for rope-assisted self-rescue or ascent is chosen because it acts as an adjustable grip on the rope. The Prusik knot does exactly that: a loop of cord wrapped around the main rope forms a friction hitch that tightens and grips the rope when you apply load, allowing you to ascend by sliding the knot along the rope as you move up. When you lessen the tension, it loosens and can be repositioned, making it reliable for progress along a rope in rescue scenarios. The other knots aren’t built for this purpose: a slipknot can easily slip and come undone under load, a bowline is great for tying a loop or attaching to an anchor but doesn’t provide the controlled gripping action needed to climb, and a figure-eight on a bight forms loops useful for anchors or attachment but isn’t used as a friction hitch to ascend a rope.
