Which statement is best supported by this table? a. the polar bear faced a long-term change. b. the tree frog faced a short term change. c. the dodo bird and tree frog faced long-term changes. d. the armadillo and dodo bird faced short-term changes. the table shows four species that have had to make changes due to an environmental change.

I think the answer is C

The correct answer is option C, The dodo bird and tree frog faced long-term changes

In the table the Dodo bird became extinct which means it will never be seen again in future. Since it is a change which will continue forever in the coming future , it can be stated as a long term change

Also the tree frog adapted something and this will also continue for a long period of time until unless some other evolutionary change is introduced. Thus it is also a long term change.
