Final answer:
Mineralization extracts calcium and phosphate from blood plasma and deposits them into the bone as hydroxyapatite, facilitated by osteoblasts.
Step-by-step explanation:
Mineralization is a process that extracts calcium and phosphate from the blood plasma and deposits it into bone. The correct answer is A. Calcium/Phosphate. These minerals are incorporated into the bone as hydroxyapatite, which gives bones their rigidity and strength. This process is facilitated by osteoblasts, which secrete the bone matrix and help in the deposition of mineral salts on the collagen fiber matrix.
