Practical approach to understanding crime's causes.

• A. Marxism
• B. Labelling theory
• C. Left realism
• D. Realism

Answer: (D)

A practical, policy-focused lens on why crime happens and how to stop it is what Realism emphasizes. It treats crime as a real, visible problem in communities and seeks evidence-based, workable solutions that can be put into action now. Realism concentrates on factors we can observe, measure, and influence—things like policing effectiveness, opportunities for crime in the environment, and offender management—to explain causes and reduce crime. This makes it a natural fit for a question about a practical approach to understanding crime’s causes because it prioritizes concrete interventions and how to achieve them in the real world.

Other theories tend to emphasize different angles: Marxism looks at how capitalism shapes crime through power and class relations; labelling theory focuses on how being labeled as a criminal can create or reinforce deviance; left realism does address crime as a real problem and proposes policy, but it foregrounds structural inequality and critical analysis rather than a straightforward, action-oriented toolkit. Realism’s emphasis on empirical evidence and practical measures to address crime makes it the most fitting choice for a practical approach to understanding crime’s causes.
