Correct answer: D — Reduce propofol target concentration

BIS 25-35 = excessive anaesthetic depth. With hypotension and bradycardia, reduce propofol target. BIS <40 associated with increased postoperative delirium and mortality (B-Aware, BAG-RECALL). Increasing remifentanil worsens bradycardia/hypotension. Vasopressors treat symptom not cause.
