The answer is white fibrous cartilage and it is called so because it is made up of dense collagen tissue which gives a characteristic colour of white and rigid support

The correct answer is option 'C' - White fibrous cartilage.

Explanation:

Cartilage is a type of connective tissue that is flexible and provides support and structure to various parts of the body. It is composed of cells called chondrocytes embedded in a matrix of fibers and ground substance. There are three main types of cartilage: hyaline cartilage, elastic cartilage, and fibrocartilage.

Intervertebral discs are located between the vertebrae in the spine and serve to cushion and absorb shock between the bones. They consist of an outer fibrous ring called the annulus fibrosis and an inner gel-like substance called the nucleus pulposus.

- White fibrous cartilage:
White fibrous cartilage is a type of cartilage that contains a dense network of collagen fibers. It is the strongest type of cartilage and provides support and strength to areas of the body where strong tensile forces are encountered. It is found in structures such as the intervertebral discs, menisci of the knee, and pubic symphysis.

- Intervertebral discs:
The intervertebral discs are composed of white fibrous cartilage, which gives them their strength and durability. The annulus fibrosis, the outer fibrous ring, is made up of concentric layers of fibrocartilage. This fibrocartilage is composed of white fibrous cartilage interspersed with collagen fibers that are oriented in different directions, giving the annulus fibrosis its strength and ability to withstand tensile forces.

- Function of intervertebral discs:
The intervertebral discs play a crucial role in the spine. They act as shock absorbers, allowing the spine to withstand the impact of daily activities such as walking, running, and jumping. They also provide stability and flexibility to the spine, allowing for movements such as bending and twisting.

Overall, the intervertebral discs contain white fibrous cartilage, which provides strength and durability to withstand the forces encountered in the spine. This type of cartilage is well-suited for its role in cushioning and supporting the vertebrae in the spine.
