The correct option is D

The vertebral column usually consists of 33 vertebrae: 24 presacral vertebrae (7 cervical, 12 thoracic, and 5 lumbar) followed by the sacrum (5 fused sacral vertebrae) and the coccyx (4 frequently fused coccygeal vertebrae). Neural canal is a dorsal tubular structure and the space enclosed by the centrum and the neural arch of a vertebra, through which passes the spinal cord.
