Correct answer: D — Necrotising enterocolitis (NEC)

Necrotising enterocolitis (NEC) is the most common surgical emergency in premature neonates. The triad of abdominal distension, feeding intolerance, and bloody stools in a preterm infant is characteristic. Pneumatosis intestinalis (intramural gas) is pathognomonic. Portal venous gas indicates severe disease. Management includes bowel rest, IV antibiotics, and surgical consultation.
