Correct answer: E — Omphalocele

A midline abdominal wall defect at the umbilicus with herniated viscera covered by a membrane (peritoneal sac) is an omphalocele. Unlike gastroschisis, the contents are covered. Omphalocele is associated with chromosomal abnormalities (trisomy 13, 18, 21) and Beckwith-Wiedemann syndrome. The membrane should be kept moist and intact. Large omphaloceles may require staged closure.
