A four-week-old female is evaluated in the neonatal intensive care unit for feeding intolerance with gastric retention of formula. She was born at 25 weeks gestation to a 32-year-old gravida 1 due to preterm premature rupture of membranes at 24 weeks gestation. The patient’s birth weight was 750 g (1 lb 10 oz). She required resuscitation with mechanical ventilation at the time of delivery, but she was subsequently extubated to continuous positive airway pressure (CPAP) and then weaned to nasal cannula. The patient was initially receiving both parenteral nutrition and enteral feeds through a nasogastric tube, but she is now receiving only continuous nasogastric formula feeds. Her feeds are being advanced to a target weight gain of 20-30 g per day. Her current weight is 1,350 g (2 lb 16 oz). The patient’s temperature is 97.2°F (36.2°C), blood pressure is 72/54 mmHg, pulse is 138/min, respirations are 26/min, and SpO2 is 96% on 4L nasal cannula. On physical exam, the patient appears lethargic. Her abdomen is soft and markedly distended. Digital rectal exam reveals stool streaked with blood in the rectal vault.

Which of the following abdominal radiographs would most likely be seen in this patient?
