Correct answer: C — Discuss bronchoscopy urgently with respiratory or ENT despite normal radiography

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

A is correct. A convincing choking history, focal wheeze and recurrent same-site pneumonia sustain high suspicion for an inhaled foreign body; a normal chest radiograph does not exclude it and bronchoscopy should be discussed. B is false because examination and imaging can be normal. C CT is not routinely recommended when bronchoscopy is likely. D delays removal. E allergy does not explain persistent focal signs after choking.
