Ct one: a. provides support to long bones b. prevents overactivity of osteoblasts. c. allows for continued bone lengthening during maturation. d. has an unknown function.

Option C

Explanation:

Complete question

The epiphyseal plate

a.  provides support to long bones.

b. prevents overactivity of osteoblasts.

c. allows for continued bone lengthening during maturation.

d. has an unknown function

Solution

In case of embryo skeletal development, epiphyseal plate is also known as the future growth plate. While other structural and functional changes are taking place in bones of a developing embryo, the cartilages found at the end of this plates continue to grow thereby increasing the length of the bone. After the formation of fetal skeleton, the epiphysis remain at  the epiphyseal plate and is responsible for longitudinal growth of bones. After the birth of baby, the epiphyseal region undergo same development processes as the development processes observed before  birth. This process is known as secondary ossification and continue till adulthood.

Hence, option C is correct
