yet different in others.
D.An animal is a living creature that moves and ingests food through a mouth.
Answer :C or D
Both sounds o.k , but which one is correct

Answer 1

Please reread them. One of them doesn't define anything, just says there are similarities and differences.

??

Answer 2

That's why it is a bit confusing ,but this is exactly how it is the text book.

Answer 3

Sentence C is simply saying there are similarities and differences among animals. That's not a definition.

Sentence D has details about an animal.

Sentence A tells what an animal isn't -- not a good definition.

Sentence B also tells what animals are not.

Answer 4

I guess D is more likely as it little bit describes an animal.

Answer 5

It sort of depends on how you want to define "effective," since the examples that would seem to work ("A" and "D") aren't actually true.
