The correct response is:
**Repeated foot movement creates bouncing that loosens knot tension.**
This option explains how the physical forces at play during walking—such as the forces exerted by movement—can cause the shoelaces to become loose and eventually untie. The constant motion and pressure from the foot can lead to the knot becoming less tight, contributing to the laces coming undone.
