ANS: D
Rationale: Spina bifida is a neural tube defect that results when the inferior neuropore does not close, producing a bony defect at the distal end of the tube. The severity of the defect varies, ranging from normal spinal cord function (spina bifida occulta) to severe malformation and exposure of the spinal cord to the surface of the body (myeloschisis).
