Answer 1

The correct option is C (i)-(b), (ii)-(c), (iii)-(a), (iv)-(d)

C. (i)-(b), (ii)-(c), (iii)-(a), (iv)-(d)

EXPLANATION: Chondrocytes are responsible for the formation of cartilage. These cells secrete extracellular matrix to maintain and sustain the cartilage. Osteocytes are the mechano-sensory cells of bone and they are used to maintain the bone function. Osteoblasts are the cells of bone, which produce new bones. The new bones are called as osteoid. They are made up of collagen and protein. Osteoclast is a large multinucleated cell, which is responsible for the dissolution and absorption of bone.
