The forces are equal and balanced. The reaction force is the upward force of the person. The action force is the downward force of the person.

Explanation:

A person standing still is being pushed down by gravity, but the floor is also pushing up on them. This creates an action-reaction pair. There is a reaction (upward support of the floor) and an action (downward pull of gravity). This is an action-reaction pair because there are forces acting in different directions with equal magnitude. We call this equilibrium .
