Answer:
B
Explanation:
A bat, alligator, and a bird obviously do not have the same anatomicial structure, which means that is ruled out because they do not have the same body structure, C will not be an answer because they are each different animals, and D has nothing to do with the question, which means B is the answer because common ancestors of these animals live in the same place as each other, which means that is the answer.
Hope this helps!
