Correct answer
Explanation
A standard matchbox has 246 friction points on its striking surfaces designed to ensure reliable match ignition. This is a specific manufacturing detail about matchbox design. Combs, toothbrushes, and pens don't have friction points in this technical sense: their function doesn't require striking against a rough surface.
