responsible for resorption of old bone matter
A
osteocyte
B
osteoblast
C
osteoclast
D
chondroblast
Explanation: 

Detailed explanation-1: -The osteoclasts are multi-nucleated cells that contain numerous mitochondria and lysosomes. These are the cells responsible for the resorption of bone. Osteoblasts are generally present on the outer layer of bone, just beneath the periosteum.

Detailed explanation-2: -Osteoclasts are multinucleated cells that are responsible for resorption of bone, and increased activity of these cells is associated with several common bone diseases, including postmenopausal osteoporosis.

Detailed explanation-3: -Osteoclast cells cause bone resorption and originate from a hematopoietic lineage, which includes multiple blood cell types from within the bone marrow. The cellular process of remodeling begins when osteoblast and osteoclast precursor cells fuse to form a multinucleated osteoclastic cell.[2] Osteoclasts.

Detailed explanation-4: -Osteoclasts are multinucleated monocyte-macrophage derivatives that degrade bone. Their specialized role is central to a process that continuously removes and replaces segments of the skeleton in the higher vertebrates.
