A woman at 34-weeks gestation in her second pregnancy comes into spontaneous labour. Labour proceeds to a vaginal delivery of a male infant weighing 2100g. He has Apgar scores of 6 at one minute, 8 at five minutes. Over the next two to three hours he develops grunting respirations, tachypnoea (respiratory rate 60/min), and subcostal recession; and at four hours of age he requires 45% oxygen to maintain oxygenation. Which one of the following is the most likely cause of the infant's respiratory distress?
(A) Meconium aspiration syndrome
(B) Tension pneumothorax
(C) Birth asphyxia
(D) Transient tachypnoea of the newborn
(E) Hyaline membrane lung disease
