• D. None of the above

Answer 1

The correct option is A Chondrin and ossein respectively

The protein present in cartilage and bone are chondrin and ossein respectively. Bone is a metabolically active tissue composed of several types of cells. These cells include osteoblasts, which are involved in the creation and mineralization of bone tissue, osteocytes, and osteoclasts, which are involved in the reabsorption of bone tissue.
Cartilage is composed of specialized cells called chondrocytes that produce a large amount of collagenous extracellular matrix, abundant ground substance, that is rich in proteoglycan and elastin fibers. Cartilage is classified into three types, elastic cartilage, hyaline cartilage and fibrocartilage, which differ in relative amounts of cartilage.

Hence the correct option is A.
