The human spinal column is typically divided into 33 segments, but it is often described in terms of 24 vertebrae that are segmented into different regions: 7 cervical, 12 thoracic, and 5 lumbar. Additionally, there are 5 sacral vertebrae that are fused to form the sacrum and 4 coccygeal vertebrae that form the coccyx.
So, from the options you provided, none of them are correct. However, if referring to the commonly discussed vertebral segments (cervical, thoracic, lumbar, sacral, and coccygeal), the main components can be considered 5 regions together. If you have to choose from your list, the closest and commonly cited total would be 31, which refers to the nerve roots (cervical: 8, thoracic: 12, lumbar: 5, sacral: 5, and coccygeal: 1).
