Correct Answer: A

Rationale: The correct answer is A: Spina bifida. A neural tube defect occurs when the neural tube, which forms the brain and spinal cord, fails to close properly during embryonic development. Spina bifida specifically involves the incomplete closure of the spinal column, leading to varying degrees of spinal cord damage. This condition is a classic example of a neural tube defect.

B: Hydrocephalus is the buildup of fluid in the brain, not a neural tube defect.
C: Cerebral palsy is a group of disorders affecting movement and posture due to brain damage, not a neural tube defect.
D: Muscular dystrophy is a genetic disorder causing progressive muscle weakness, not a neural tube defect.

In summary, spina bifida is the correct answer as it directly relates to the incomplete closure of the neural tube during development, while the other choices are unrelated conditions affecting different aspects of the nervous system or muscular system.
