Which statement describes the poly/nylon combination construction correctly?

• A. Combines nylon and polyester material
• B. New England Ropes KM III
• C. Continuous filament polyester sheath braided over a nylon core
• D. All of the above are correct descriptions

Answer: (A)

Poly/nylon construction means the rope uses two different polymers. The best description is that it combines nylon and polyester material, since that states the essential idea: two materials are used in the rope. This captures the general construction without tying it to a specific product or to one particular core/sheath arrangement. While mentioning a specific product or detailing a particular core-and-sheath setup can be true for some poly/nylon ropes, the prompt asks for the broad description of the construction, which is simply that nylon and polyester are combined.
