Answer:
If the caudal portion of the neural tube failed to develop properly the A) spinal cord may be affected.
Explanation:
The neural tube is a structure in the embryo that gives origin to the central nervous system. The neural tube has two regions, the cephalic one, which gives origin to the brain and a part of the spinal cord, and the caudal section, which gives the rest of the spinal cord. If there is a problem during the development of the neural tube or the closure of the caudal section of it, the spinal cord will not be formed correctly.
