Multiple Choice

Which statement best supports the speculation that large dinosaurs may have had some degree of endothermy?

B) Because their surface area-to-volume ratio probably would not have allowed for enough heat exchange with their environment, they would have needed to generate some internal energy.
C) They would have had a high intake of nitrogen, which leads to endothermy.
D) We have evidence that they evolved from endothermic ancestors.
