Correct answer: BProceed with early controlled intubation using video laryngoscopy and surgical backup

Explanation lettering: D = shown as A · A = shown as B · E = shown as C · C = shown as D · B = shown as E

A is correct because this cluster signals evolving upper-airway injury; early controlled intubation is safer before edema progresses, with a rescue airway prepared. B risks deterioration during endoscopy. C may temporize but is not definitive. D waits for a late sign. E does not secure the airway.
