b. normal
c. applied
d. frictional

If a person is pushing a desk across the room, then there is an applied force acting upon the object.

Option C

Explanation:

As Newton stated in its first laws of motion that any object cannot undergo change in its state of motion or rest until and unless an external unbalanced force acts on the object. So, in order to push the table across the room, the unbalanced force must be applied on the table by the person.

And this external unbalanced force should be more than the frictional forces between the bottom of desk and surface of floor. So the force that is used to push a desk across the room is termed as applied force as the force is applied on the surface of the desk.
