The correct response is:
It has a change in momentum equal to that of the rock, in the opposite direction.
This is based on the principle of conservation of momentum, which states that the total momentum of a closed system remains constant. When the rock bounces off the car, the change in momentum of the rock results in an equal and opposite change in momentum of the car.
