• A. False
• B. Not specified
• C. Not important
• D. True

Answer: (D)

Gaffs on a climber’s boot are what give secure footing in the tree, so they must bite into the wood reliably. That bite comes from having a sharp point that can penetrate, being properly sized to fit the boot and leg geometry so they contact the wood at the correct angle and depth, and having a shape that concentrates force where it’s needed and aligns with the boot’s contour. When these aspects are right, the gaffs provide stable purchase, reduce slipping, and help prevent dangerous gaps or failures in the climbing setup. So the statement is true.
