The correct answer is a.
Bone remodelling (or bone metabolism) is the term describing the continuous reshaping of the bones, by removing mature bone tissue and forming new bone tissue. Two main types of cells participate in this process, the osteoblasts and osteoclasts. Osteoblasts secrete new bone and osteoclasts break down the mature bone.
