Answer»

The correct option is (a) 2

For explanation: Each long bone has articular/HYALINE CARTILAGE at the OUTER extremities of the bone and an epiphysial cartilage at the extremities of the SHAFT. Hyaline Cartilage helps reduce friction and the epiphysial cartilage helps the bone grow. At maturity, the epiphysial cartilage of the bone solidifies.
