# Bone replaces cartilage by which of the following processes? 
a. Interstitial growth
b. Endochondral development
c. Intramembranous bone formation
d. Membranous bone formation

The correct answer is: B. Endochondral development.

Interstitial growth is growth within the cartilage matrix by each cartilage cell enlarging
and forming matrix around each cell.

Bone replaces cartilage by a process termed endochondral bone development.

Intramembranous bone is formed when collagen fibers of connective tissue organize into closely knit meshwork, and this matrix gradually calcifies into bone.

Intramembranous bone formation is also known as membranous bone formation.
