PT33.S1.Q11 - researchers have discovered that caffeine

Hi all I am a bit confused about the sufficient and necessary condition for (C).
According to JY, (C) should be interpreted as "no[Physically addictive --> psychoactive]" , but shouldn't the relative clause "to which people can become physically addicted" introduce the necessary condition to make the argument no[psychoactive --> physically active]? Thanks!

In (C), "to which people can....addicted" is modifying "substances."

So (C) is saying:
NOT [substances (which people can become addicted to) → psychoactive]
