Correct answer: B — Refer urgently for assessment of possible C. difficile infection

Clindamycin is associated with C. difficile infection and severe diarrhoea requires assessment. In this vignette, "Refer urgently for assessment of possible C. difficile infection" is the safest single best answer. The other options are less appropriate because they miss the key clinical risk, conflict with UK medicines guidance, or delay needed review.
