The best choice that explains the forces at work when someone is standing still on the ground is:
**Gravity pulls down on the person, but the ground pushes up with equal force.**
This statement describes the balance of forces where the downward gravitational force is countered by the upward normal force from the ground, resulting in a net force of zero and the person remaining stationary.
