Correct answer: C — Nitrofurantoin if suitable for gestation and renal function

Nitrofurantoin is commonly used for cystitis in pregnancy when appropriate, but gestation and renal function matter. 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.
