Isaac Newton discovered the three laws of motion. Which example BEST illustrates Newton's third law of motion, which describes action and reaction forces?

Explanation: A boy sitting on a chair ... Assuming the boy has a weight of 50N and he sits on the chair. He will exert a downward force of + 50N while the chair will exert an upward force of - 50N. This shows that for every action there must be equal and opposite reaction ... Another example is when you recoil a gun
