Correct answer: E — Diltiazem

A rate-limiting calcium-channel blocker may be considered for rate control where beta-blockers are unsuitable, subject to cardiac status and contraindications. In this vignette, "Diltiazem" 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.
