Choose the correct answer from the options below:

Sequentially arrange the sections of the vertebrae of the spinal column from top to bottom:
Thoracic vertebrae
Sacral vertebrae
Cervical vertebrae
Lumbar vertebrae

Correct option is B

The vertebral column is divided into five main sections, arranged from the top (near the skull) to the bottom (lower back and pelvis). The correct order is:

Cervical Vertebrae (C) – Located in the neck, consisting of 7 vertebrae (C1-C7).
Thoracic Vertebrae (A) – Located in the upper and mid-back, consisting of 12 vertebrae (T1-T12).
Lumbar Vertebrae (D) – Located in the lower back, consisting of 5 vertebrae (L1-L5).
Sacral Vertebrae (B) – Located at the base of the spine, fused into the sacrum (S1-S5).

Thus, the correct sequence from top to bottom is C → A → D → B.
