If the caudal portion of the neural tube failed to develop properly the
.a) spinal cord may be affected
b) cranial nerves would not form
c) hindbrain would not be present
d) telencephalon would cease developmen

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.
