You are seeing a 2-month-old male infant who has trisomy 21 for a health supervision visit. The boy's mother expresses concern that the infant has been having "noisy breathing" during the past 2 to 3 weeks. The infant has been exclusively formula-fed and has had no choking or difficulty feeding. According to the mother, the noise, which occurs on inspiration, is louder when the infant is supine and when crying. She has not noticed any rhinorrhea, cough, or other upper respiratory viral illness symptoms. The infant was born via an uneventful vaginal delivery that did not require forceps. Apgar scores were 8 and 9 at 1 and 5 minutes, respectively. On physical examination, the infant, whose physical appearance is consistent with trisomy 21, is resting comfortably. His vital signs are appropriate for age, but you hear an audible noise during inspiration. Of the following, the MOST likely explanation for the infant's respiratory symptoms is
A) laryngomalacia
B) subglottic tracheal web
C) tracheomalacia
D) vascular ring
