Correct answer: C — Bronchiectasis

The HRCT findings of bronchial dilatation, lack of tapering and peripheral airway visibility are diagnostic imaging features of bronchiectasis. UIP would show reticulation and honeycombing rather than dilated airways as the primary abnormality. Pulmonary oedema or vascular malformation would not produce this airway pattern.
