C. Pinpoint pupils, hypertension, and constipation: Hypertension is not a typical feature of opioid overdose; hypotension is more common.
D. Constipation, pupillary dilation, and hypotension: Constipation is common with opioids but pupillary dilation and hypotension are not part of the typical toxicity triad.
