Answer:
D. mature bone cells replace cartilage
Explanation:
Ossification is the process and the result of ossifying, a verb that refers to the process that leads an organic element to transform into a bone or to obtain an appearance similar to it.
Through ossification, therefore, a new bone component can be created. Osteoblasts are responsible for developing this procedure, which can be accomplished in various ways.
It is believed that the bones arose from the evolution of certain cartilages, which began as a reserve of calcium and other minerals and eventually evolved to protect the organs. From bone evolution, vertebrates were able to adapt to the earth's surface and move in a different way.
One of the types of ossification known is called endochondral, and it is a development that involves the progressive replacement of hyaline cartilage with bone tissue, in a process that takes place from the inside out. When development takes place the other way around (that is, from the outside inwards), one speaks of pericondral ossification.
