Correct answer: C — ICD-11

The correct answer is C, ICD-11. ICD-11 is the eleventh revision of the World Health Organization's International Classification of Diseases and is the international standard for recording and comparing mortality and morbidity data. DSM-IV-TR was an older American Psychiatric Association diagnostic manual rather than the WHO system. Research Domain Criteria is a research framework organised around behavioural and neurobiological dimensions, not an international disease-coding classification. The Feighner criteria were historical operational diagnostic criteria developed to improve psychiatric research reliability. Kraepelin's dementia praecox was a historical diagnostic concept that contributed to the development of the modern concept of schizophrenia, not a current classification system for international health statistics.
