The correct answer is "cartilage cells are replaced by bone cells".

The plate near the end of long bones is called the epiphyseal plate and is composed of cartilage in children. Cartilage and cartilage cells are capable of dividing and adding cartilage matrix which contributes to the lengthening of the bone; then this cartilage will slowly be replaced by bone through aging and hormonal factors.
