Hint: A connective tissue that is commonly found in many parts of the body such as joints between bones. It forms a coating that surfaces our joints and provides cushioning of bones against an impact.

Complete answer: The spinal column or vertebral column forms the central axis of the skeleton in all the vertebrates. It helps in providing attachments to the muscles, serves as the site for haematopoiesis, and protects the spinal cord. It is a series that has approximately 33 bones that are known as vertebrae. A vertebra consists of an anterior part and a posterior part. The vertebrae are separated by intervertebral discs. The intervertebral disc contains fibrocartilage. It is divided into five different regions and each region is characterized by different shapes of vertebrae. It performs four major functions- protection, support, axis, and movement. Vertebrae are the weight-bearing component. The vertebral column is divided into regions which are as follows-
1. Cervical
2. Thoracic
3. Lumbar
4. Sacrum
5. Coccyx
Only the upper 24 bones are movable and sacrum and coccyx are fused. The cervical region covers between C1-T2 and the thoracic curve covers the region between T2-T12. The lumbar region covers T12-L5. The sacral region starts at the sacrovertebral articulation and it ends at the coccyx region. The sacrum is the region at the base of the spine. It is a group of specialized vertebrae that helps in joining the vertebral column to the pelvic girdle.
Hence, the correct option is (A)-Cartilaginous.

Note: The cartilage is a smooth and resilient elastic tissue and covers and protects the joints and nerves and forms the structural component of the rib cage, nose, external ear, bronchial tubes, intervertebral discs, and many other parts of the body.
