once the osteoblasts are trapped within the ossified bone tissue they again differentiate and become...
□ osteocytes
□ chondrocytes
□ fibroblasts
□ osteoclasts
rewatch

Explanation:

Osteoblasts are bone-forming cells. When they get trapped within the hard, ossified bone matrix they produce, they undergo differentiation into mature bone cells called osteocytes. Chondrocytes are cartilage cells, fibroblasts are connective tissue cells that produce collagen, and osteoclasts are bone-resorbing cells, none of which are the result of trapped osteoblasts differentiating.

Answer:

osteocytes
