Suppose you are pushing a loaded shopping cart. Which of the following is true?

If action force always equals reaction force, you cannot move the cart because the cart pushes you backward just as hard as you push forward on the cart

You push the cart slightly harder than the cart pushed you backward, so the cart moves forward

You push before the cart has time to react, so the cart moves forward.

You are in contact with the earth through your high-friction shoes, while the cart is free to roll on its round wheels, so the cart moves.
