The cervical nerves are the spinal nerves arising from the cervical vertebrae. Although there are 7 cervical vertebrae, however, there are 8 cranial nerves where 8th emerges below the C7 vertebra.

The thoracic nerves are the spinal nerves emerging from the thoracic vertebrae. They are 12 in number.

The lumbar spinal nerves arise from the spinal cord between each pair of spinal vertebrae and travel through the intervertebral foramen. They are 5 in number.

The coccygeal plexus is a plexus of nerves near the coccyx bone. It is the 31st pair of spinal nerves, only 1 in number. Thus, the correct answer is option B.
