14. The bone development in the body occurs duirng the postnatal growth. During the process of endochondral ossification, the development of bones occurs from the hyaline cartilage. The length of bones occurs due to activity in epiphyseal plate. This process increase the length og bone, while the diameter of bone is increased by the Appositional growth.
THe answer is B and C.
