Correct answer: BClarify the exact product and strength before supply

Insulin products and strengths are not directly interchangeable without clear prescribing. 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.
