Explanation:

Opioids are a class of drugs that act on opioid receptors in the brain and other parts of the central nervous system (CNS). Their primary effect is to depress or reduce the activity in the CNS. This depression leads to effects like pain relief, sedation, and in some cases, respiratory depression. Stimulants would increase CNS activity, and opioids clearly do affect the CNS, so the correct option is the one stating they depress CNS activity.

Answer:

A. depress activity in the central nervous system.
