Final answer:
The newborn's failure to pass meconium, coupled with the absence of neural crest cell migration, indicates the condition Hirschsprung's disease. Other conditions listed like Intussusception, Malrotation, and Volvulus are different types of bowel obstructions not directly related to neural crest cell migration.
Step-by-step explanation:
When a newborn fails to pass meconium due to a lack of neural crest cell migration, the condition referred to is Hirschsprung's disease. This congenital disorder affects the large intestine and obstructs normal bowel movements. Hirschsprung's disease occurs because neural crest cells fail to migrate completely during the development of the enteric nervous system. This leads to a lack of ganglion cells in the distal segments of the intestine, preventing normal peristalsis and resulting in the accumulation of stool, including meconium, which is the newborn's first bowel movement.
In comparison, Intussusception is a condition where part of the intestine folds into another section; Malrotation involves abnormal rotation of the midgut during fetal development, which can cause obstruction; and Volvulus refers to twisting of the gut on itself. Each of these conditions can cause obstruction and symptoms like abdominal pain and vomiting, but they do not directly involve the failure of neural crest cells to migrate and would not be characterized by the failure to pass meconium alone.
The correct answer to the question is A) Hirschsprung's disease.
