Step-by-step explanation:
The part of the spine that is made up of 12 vertebrae is the thoracic spine. The vertebral column, also known as the spine or backbone, is divided into several regions. There are seven cervical vertebrae in the neck (C1-C7), followed by twelve thoracic vertebrae (T1-T12) in the chest area, and five lumbar vertebrae (L1-L5) in the lower back.
The sacral spine consists of five fused sacral vertebrae, and the coccygeal region, or tailbone, is formed from the fusion of four coccygeal vertebrae. The primary role of the thoracic spine is to provide stability and support for the upper body and serve as an attachment for the rib cage. option b is answer
