Correct answer: D). High blood calcium levels and a lack of bone growth
The osteoblast is the cell that is known for the synthesis and mineralization of the bone tissue at the time of bone formation and later in the process of bone remodeling.
It forms a packed sheet on the bone surface, from where the cellular process of bone formation extends. They are known to regulate the passage of calcium in and out of the bone.
Hence, correct answer would be option D.
