Answer:
(c) the force you exert on the box is greater than the force of the box pushing back on you.
Step-by-step explanation:
When a force is exerted on an object such that it starts accelerating without any change in the state of rest of the source of the force that always means that the reaction force of the object on the source is less than the action force.
This condition is in accordance with Newton's second law and Newton's third law.
