What are Chondrichthyes?

Chondrichthyes is a class of cartilaginous fishes, which have skeletons made primarily of cartilage.

They differ from the Osteichthyes, or bony fishes, which have skeletons made mostly of bone tissue.

Calcium phosphate mineralizes the teeth of cartilaginous fish. Mineralization of teeth is an operation in which living organisms incorporate cellular material with environmental minerals.

This process occurs to form a matrix structure, which usually results in harden structures such as tooth enamel or bone matrices.

Thus, the correct option is B.
