Final answer:
Legal action against fraud perpetrators discourages future occurrences of fraud by increasing the costs of criminal behavior, acting as a deterrent, and reflecting the public good aspect of crime prevention.
Step-by-step explanation:
The best argument for taking legal action against fraud perpetrators is d. Prosecution of perpetrators discourages future occurrences of fraud. This stems from the economic concept of cost-benefit analysis applied to criminal behavior. When the costs of crime increase due to higher chances of prosecution and stiffer penalties, potential fraudsters may be deterred thereby reducing incidents of fraud. This argument aligns with criminal justice approaches that prioritize deterrence and reflect the public good nature of crime prevention. Legal action not only serves to punish the wrongdoer but also acts as a cautionary tale for others who might consider engaging in fraudulent activities.
