Tom Asks His Professor Why the Debate About Whether Addiction

Tom asks his professor why the debate about whether addiction is or is not a disease is so important. How is his professor likely to respond?

A) "The debate is not trivial because if addiction is a disease, addicts must totally refrain from any substance use at all; if it is not a disease, they could use substances in moderation."
B) "The debate is not trivial because insurance companies will only pay for rehabilitation and treatment if addiction is classified as a disease."
C) "The debate is not trivial because much more stigma is attached to addiction when it is seen as a disease."
D) "The debate is not trivial because much more stigma is attached to addiction when it were seen as being under a person's control rather than as a disease."
