Step-by-step explanation:
The correct answer is option C. There are 31 spinal nerves in the human body. These spinal nerves are named according to the level of the spinal cord where they emerge. There are eight pairs of cervical nerves (C1-C8), twelve pairs of thoracic nerves (T1-T12), five pairs of lumbar nerves (L1-L5), five pairs of sacral nerves (S1-S5), and one pair of coccygeal nerves. Each spinal nerve emerges from the vertebral column through an intervertebral foramen, and they play a crucial role in transmitting sensory and motor information between the spinal cord and the rest of the body.
