When a 12 N horizontal force is applied to a box on a horizontal tabletop, the box remains at rest. The force of friction acting on the box is 1) 0N
2) Between 0N and 12N
3) Exactly 12 N
4) Greater than 12N

The force of friction acting on the box is greater than 12N

For an object to move, the applied force has to be larger than the maximum force of static friction. If the force applied is less than the maximum force of static friction, the object would remain at rest.

Therefore, if a 2 N horizontal force is applied to a box and the box remains at rest, this mean that the force applied is less than the force of friction acting on the box. Hence the force of friction acting on the box is greater than 12N

Explanation:

when a force is applied to a body but still stays at rest or moves at a constant speed , the frictional force is equal to the force applied
