A is correct. Jaw stiffness and reduced opening are common after lower wisdom-tooth surgery and may persist during the first 1–2 postoperative weeks. In the absence of infective features, management is conservative: appropriate analgesia, moist warmth and gentle jaw-opening exercises, with review and clear safety-netting. Antibiotics are not indicated for trismus alone; reassess urgently if pain or swelling worsens, or if fever, malaise, purulence or a bad taste develops. Forceful opening under general anaesthesia and socket re-exploration are disproportionate without another diagnosis. A muscle relaxant alone does not provide the usual supportive approach, while discharge without advice or review omits symptomatic care and safety-netting.
