The best statement that describes the effect of the force is: The force will cause a change in the momentum of the object.
This is because any net force acting on an object results in an acceleration (according to Newton's second law, \( F = ma \)), which changes the object's velocity. Since momentum is the product of mass and velocity, a change in velocity (whether it be an increase or decrease in speed or a change in direction) will also lead to a change in momentum.
