Correct answer: D — Increased statin exposure with myopathy risk

Verapamil can increase simvastatin levels and dose restrictions may apply. 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.
