The answer to this question should be a gravitational force.
A gravitational force is something that sort of attracts two things of mass. This force must never ever pull the objects of mass apart. It must always try to pull them together. So, judging by the question we can tell that the two masses in this situation are the leaf and the ground. When the leaf fell on the ground this was the gravitational force pulling the leaf down so it connects with the ground.
The answer for the given question above would be option C. GRAVITATIONAL FORCE. Based on the given scenario above of a leaf that falls to the ground when Tonya let it go, the force that pulled the leaf to the ground is the gravitational force. This kind of force is a force <span>that attracts any object with mass. Hope this helps.</span>
