Answer - C - Axis II in DSM-IV for reporting personality disorders and mental retardation. Clinicians may also use this axis to report maladaptive personality features that do not quite meet the requirements of a personality disorder, as well as defense mechanisms that are cause for concern.
When the fifth edition, the DSM-5, was compiled, it was determined that there was no scientific basis for dividing the disorders in this manner, so the multi-axial system was done away with. Instead, the new non-axial diagnosis combines the former Axes I, II, and III and include separate notations for the type of information that would have previously fallen into Axes IV and V. While the axes were eliminated, some clinicians may still refer to them.
