Correct answer: C — Use one or two sprays under the tongue while sitting, and seek emergency help if pain persists after repeat dosing

GTN can cause hypotension and headache, so the patient should sit before use and know when to seek urgent help. The best answer addresses the key safety, legal or pharmaceutical care issue in the vignette. The other options would either delay appropriate care, create a new risk, or fail to resolve the issue. This is consistent with the cited UK reference for safe pharmacy practice.
