Quizplus · Accepted Answer

The lower jaw of a reptile is made up of multiple bones whereas the lower jaw of a mammal is a single bone. The number of teeth in a mammal's lower jaw can vary depending on the species, but it is not consistently 16. The lower jaw of a reptile does contain teeth, so options B and C are incorrect. Option E specifies a specific number of teeth in a reptile's lower jaw, which is not universally true.
