Concept:
Enrico Ferri, a key figure in the "Positive School" of criminology, expanded on Lombroso's biological theories by including social, economic, and environmental factors. He classified criminals based on the root cause of their criminality.
Step 1: Identifying Ferri's 5-Fold Classification.
Ferri proposed five categories of criminals:
• Born Criminals (C): Those with an inherent biological predisposition.
• Insane Criminals: Those suffering from mental illness (not "Sane" as in option A).
• Passionate Criminals (D): Those who commit crimes due to sudden emotional impulse or stress.
• Habitual Criminals (E): Those who have acquired a habit of crime through their social environment.
• Occasional Criminals: Those who commit crime due to opportunity or social pressure.
Step 2: Analyzing the Options.
Options C, D, and E are direct matches to Ferri's primary classification. "Anthropological" (B) is a broad term for the school of thought but not a specific category name in Ferri's five-fold system, and "Sane" (A) is the opposite of his "Insane" category.
