Answer:

The correct answer is option - D. they contain bundles of axons.

Explanation:

Spinal nerves are is neuron that transfer motor, autonomic, and sensory signals in between the spinal cord and body. There are approximately 31 pairs of spinal nerves present in the human body on each side of the vertebra. These nerves contain numerous bundles of axons that help in sending the signals.

The cranial nerves are made up of 12 pairs of nerves that originate from the nervous tissue of the brain. They must enter or exit through an opening in the skull to the cranium. These nerves have bundles of axons that help in the different function by assisting the carrying the signals to target sites such as facial expression and many more.

Thus, the correct answer is - D. they contain bundles of axons.
