Correct answer: B — Take with or after food and report persistent intolerance
Taking metformin with food can improve gastrointestinal tolerability. 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.
