25
33
42

The correct answer is C. There are 33 vertebrae in the human vertebral column. The vertebrae are divided into five groups: cervical, thoracic, lumbar, sacral, and coccygeal. The cervical vertebrae are the first seven vertebrae in the spine. They are located in the neck and support the head. The thoracic vertebrae are the next 12 vertebrae in the spine. They are located in the chest and support the rib cage. The lumbar vertebrae are the next five vertebrae in the spine. They are located in the lower back and support the weight of the upper body. The sacral vertebrae are the five fused vertebrae at the base of the spine. They form the sacrum, which is a triangular bone that connects the spine to the pelvis. The coccygeal vertebrae are the four fused vertebrae at the very end of the spine. They form the coccyx, which is a small bone that projects down from the sacrum.

Option A is incorrect because there are 33 vertebrae in the human vertebral column, not 22. Option B is incorrect because there are 33 vertebrae in the human vertebral column, not 25. Option D is incorrect because there are 33 vertebrae in the human vertebral column, not 42.
