A 6-Hour-Old Kid Is Having Feeding Challenges in the Newborn

A 6-hour-old kid is having feeding challenges in the newborn nursery. The patient was delivered through cesarean section at 39 weeks gestation to a 33-year-old primigravida owing to fetal heart tracing failure and late decelerations. Although the Apgar scores were 8 and 9, an examination revealed an infant who was drooling and coughing excessively. At rest, cardiac, respiratory, and abdominal tests are normal. When the newborn tries to nurse, he experiences many bouts of coughing and perioral cyanosis, with an oxygen saturation of 85% on room air. Which of the following is most likely to be the source of this patient's condition?

A) Atresia of small intestine
B) Collapse of supraglottic structures during respiration
C) Failure of primitive foregut to separate from airway
D) Obstruction of posterior nasal passages
E) Thoracic herniation of abdominal viscera
