Answer:
C. Diphyodont
Read Explanation:
Mammals are characterized by diphyodont dentition.
Diphyodont: This term means having two successive sets of teeth, first the deciduous (milk) teeth and then the permanent teeth. This is a key characteristic of most mammals.
Homodont: This refers to having teeth that are all of the same shape and size, which is common in fish and reptiles, but not in mammals (with a few exceptions like dolphins).
Polyphyodont: This describes having teeth that are continuously replaced throughout life. This is characteristic of many vertebrates like sharks and crocodiles.
Acrodont: This refers to teeth that are attached to the top surface of the jawbone, without sockets. This is seen in some amphibians and reptiles.
