Final answer:
Nonstick coating on steel has the lowest coefficient of friction.
Step-by-step explanation:
Out of the given options, nonstick coating on steel has the lowest coefficient of friction.
According to the table provided, Teflon on steel has a lower coefficient of friction compared to the other materials listed.
The coefficient of friction determines the resistance to motion between two surfaces. A lower coefficient of friction indicates less resistance and smoother movement.
