Within the Context of Drug Legalization, Some Critics of Legal

Within the context of drug legalization, some critics of legal moralism argue that, if legal moralism were applied in different contexts, other practices, like cheating at golf, plagiarizing, and lying to a spouse, would also have to be illegal. How is this intended as an objection to legal moralism?

A) It's not clear why the immorality of drug use is sufficient for making it illegal, when the other also immoral practices are not against the law.
B) It's not clear that drug use is immoral, which is the sole reason why legal moralists think it should be against the law.
C) The consequences of keeping drug use illegal would likely result in more instances of these immoral practices.
D) Drug use isn't inherently immoral, but these other practices are.
