Correct answer: C — Sit down, use one or two sprays under the tongue, and seek emergency help if pain persists

GTN can cause dizziness and hypotension, so the patient should sit before using it. It is sprayed under the tongue for rapid relief. Persistent pain despite repeat use may indicate ACS and requires emergency assessment.
