Final answer:
Option D ('The DSM uses flexible categories that do not allow for proper standardization') is not a problem with the DSM-V as it seeks to standardize categories to help in the consistent diagnosis of mental disorders.
Step-by-step explanation:
The DSM-V, or the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, has been criticized for various issues related to the diagnosis of mental disorders. However, option D ('The DSM uses flexible categories that do not allow for proper standardization') is not a problem with the DSM-V. In fact, the DSM strives for standardization in its categories to aid mental health professionals in diagnosing disorders consistently. The DSM-V, while having detailed descriptive categories, has also been criticized for not addressing causes of disorders, potentially pathologizing normal human behaviors, and the implications of labeling individuals.
