Correct answer: B — Additive CNS and respiratory depression risk

Alcohol can increase opioid sedation and respiratory depression. The patient should avoid alcohol and be counselled on safety. In this scenario, the correct option is additive CNS and respiratory depression risk. The other options are plausible but do not address the key clinical, legal or safety issue as directly.
