Explanation:

Osteoblasts build bone and osteoclasts break it down. After bone formation, this remodeling process continues throughout life to maintain bone health and respond to mechanical and metabolic demands. The second option is incorrect as osteoblasts and osteoclasts don't simply turn into osteocytes and bone is not static. The third option is wrong because bone breakdown is not a steady 10% per - year decrease.

Answer:

Bone is continually remodeled by osteoclasts and osteoblasts.
