The correct option is B) "This duck-billed dinosaur had about 2,000 teeth....".
The statement "This duck-billed dinosaur had about 2,000 teeth...." provides explicit information about the dental characteristics of hadrosaurs. The sheer number of teeth mentioned (about 2,000) is significantly greater than the number of teeth in modern humans (32 teeth). This information suggests that hadrosaurs had a complex dental structure, quite distinct from that of modern humans.
The claim that "a modern dentist would certainly enjoy having a hadrosaur as a client" is likely based on the idea that a dentist might find it intriguing or challenging to work with such a unique dental structure. Modern dentists are accustomed to dealing with dental issues in humans, and the contrast between the dental anatomy of hadrosaurs and humans would likely make the experience of treating a hadrosaur an interesting one for a dentist.
In essence, the evidence in option B supports the claim by highlighting the distinctive dental features of hadrosaurs, particularly their large number of teeth, and suggests that this unique characteristic could be of interest or enjoyment to a modern dentist.
