Step-by-step explanation:
The primary unit of analysis in psychological and psychiatric theories of crime causation is B) Individual behavior. Psychological and psychiatric frameworks focus on individual mental processes, personality traits, and behavioral patterns to understand criminal behavior. Contrarily, sociological theories like social disorganization theory and conflict theory tend to look at larger societal structures, cultural norms, and economic systems. Social disorganization theory suggests that a person's environment can predispose them to engage in criminal acts, examining the influence of socioeconomic and family factors on crime rates. Conflict theory, attributed to the ideas of Karl Marx and C. Wright Mills, posits that crime is a result of societal inequalities and the struggle between powerful and less powerful social classes.
