Option (c) is correct.

A. "Some animals are birds." This statement asserts the existence of animals that are birds. It does not exclude the possibility of animals that are not birds.

B. "Some animals are not non-birds." This statement can be simplified as "Some animals are birds." It conveys the same meaning as statement A, indicating that there are animals that are birds.

C. "Some non-birds are not non-animals." This statement can be simplified as "Some non-birds are animals." It implies that there are non-birds that are animals, which aligns with statement D.

D. "Some birds are animals." This statement asserts the existence of birds that are animals. It does not exclude the possibility of birds that are not animals.

Therefore, option (c) A, B, and D are logically equivalent because they all convey the idea that there exist animals that are birds. Statement C is not logically equivalent to the other statements because it introduces the concept of non-birds, which is not present in the other statements.
