Final answer:

The screwheads should be driven slightly below the face of the gypsum panel without breaking the paper backing to ensure a smooth finish and maintain structural integrity.

Step-by-step explanation:

When attaching gypsum panels to either wood or steel framing with screws, the correct depth to which screwheads should be driven is C. Slightly below the face of the panel. It is important that the screwheads are set below the surface to allow for a smooth finish when taping and finishing joints, but not so deep as to break the paper backing of the gypsum board. Breaking the paper can compromise the holding power of the screw and the integrity of the wall or ceiling assembly.
