The correct option is D cartilage
Cartilage is a specialized, flexible connective tissue that keeps joint motion fluid. It does so by coating the surfaces of the bones in our joints and by cushioning bones against impact.
In vertebrates, most of cartilages in the embryo stage are replaced by bones in the adult stage. They are found at the tip of nose, ears, limb joints etc. There are three types of cartilage: hyaline cartilage, elastic cartilage and fibrocartilage.
Most embryonal cartilages are replaced by bones in adults, which are hard, non-pliable and composed of calcium salts and collagen fibres. The bone tissue interacts with the skeletal muscle to promote movement in the body.
Dense regular connective tissues include tendons which connect muscles to bones and ligaments which connect bones to bones.
