Answer:
D. Lungs
Explanation:
Just from reading this question, I was able to gather that the answer would be Lungs because it is the one body part that would allow amphibians to survive on land. If they just had gills, they would not be able to survive on land because the gills would always require water. Most amphibians do not have fins, and they (particularly frogs) lose their tails after they grow to be adults. So, that is why my answer would be lungs.
