Bones will continue to grow and lengthen until what occurs? a. the epiphyseal cartilage is ossified. b. the child turns 18 years old. c. the process of bone remodeling ceases. d. there is only a small amount of epiphyseal cartilage left.

The right answer is A.

Growth is mainly due to the growth hormone. It allows the growth cartilages to form bones.

The child grows rapidly the first year then his growth reaches a relatively stable growth when he has the age of puberty. After, the sex hormones appear and develop the growth cartilages, shaping them permanently. it is then the stop of growth.
