The correct option about spinal nerves is:

Explanation

As the dorsal root emerges from the intervertebral neural foramina, it forms the dorsal root ganglion (DRG). The DRG contains the cell body of the sensory neurons. These neurons relay sensory neural messages from the periphery to the central nervous system (brain and spinal cord). The ventral (anterior) or motor root consists of axons from the lower motor neurons in the ventral horn of the spinal cord. The ventral roots typically have fewer fibers than the dorsal roots, but they are of a larger caliber because they contain thick axons originating from the large lower motor neurons.
