(A) the amount of force with which the car pushes on the truck is equal to that with which the truck pushes back on the car.

(B) the amount of force with which the car pushes on the truck is smaller to that with which the truck pushes back on the car.

(C) the amount of force with which the car pushes on the truck is greater to that with which the truck pushes back on the car.

(D) the car’s engine is running so the car pushes against the truck, but the truck’s engine is not running so the truck cannot push back against the car. The truck is pushed forward simply because it is in the way of the car.

(E) neither the car nor the truck exerts any force on the other. The truck is pushed forward simply because it is in the way of the car.
