Step-by-step explanation:
The DSM-5 is based on a classification system. This is the correct answer to the question, aligning with the options provided. The DSM-5 employs a categorical approach to classifying mental disorders, organized by different categories of disorders. These categories are meant to help clinicians and researchers effectively diagnose and treat mental health conditions. Though there have been discussions and revisions regarding the classification system in the DSM-5, especially regarding personality disorders, the final publication continues to utilize this categorical framework.
As an example, the taxonomic classification system used in biology also employs a categorical approach, sorting living organisms into hierarchical categories. In the context of the DSM-5, mental disorders are categorized in a similar hierarchical manner, though the purpose here is to aid in the assessment and treatment of mental health issues.
