C. it enables rubber pads to be rubbed off
Explanation:
Friction is a phenomenon which resists motion when an object is rubbed against another. So friction has instances where it is desired and instances where it is not desired.
Friction helps and is hence desirable when drawing, walking, driving or picking up fallen objects. However, it is not desirable when it causes rubber pads to be rubbed off and causes wear and tear.
Option C is the answer.
