Here are the essential concepts you must grasp in order to answer the question correctly.
Osteoblasts
Osteoblasts are specialized cells responsible for the formation of new bone tissue. They synthesize and secrete the bone matrix, which includes collagen and other proteins, and play a crucial role in mineralizing the bone. Their primary function is to build and repair bone, making them essential for maintaining bone density and health.

Osteoclasts
Osteoclasts are large, multinucleated cells that are responsible for bone resorption, the process of breaking down bone tissue. They secrete acids and enzymes that dissolve the bone matrix, releasing minerals back into the bloodstream. This process is vital for regulating calcium levels and for the remodeling of bone in response to stress and injury.

Bone Remodeling
Bone remodeling is a continuous process where old bone tissue is replaced by new bone tissue, involving the coordinated actions of osteoblasts and osteoclasts. This dynamic process allows bones to adapt to mechanical stress, repair micro-damage, and maintain mineral homeostasis. Understanding this balance is crucial for recognizing how bone health is maintained and how disorders can arise.
