The core of a kernmantle rope makes up what percentage of its strength?

Explanation:
In kernmantle rope, the main load-bearing element is the core, which carries the majority of the tension. The sheath mainly protects the core and adds abrasion resistance, while not sharing the load as much. Because of this design, the core typically accounts for about three-quarters to four-fifths of the rope’s breaking strength, which falls in the 75–80% range. That’s why 75–80% is the best fit. The other ranges either underestimate or overestimate the core’s contribution.
