I would say that the answer is A. Answers B and C are definitely wrong because DNA in eukaryotic cells are in the nucleus while two identical daughter cells are created from asexual reproduction. Answer D is wrong because you can compare two different organisms like a human and a dog. Since both are eukaryotic they will have eukaryotic cell structures with their organelles. I believe that A would be correct, if you remember the the level of organizations, then you know that cells are simple, as cells become tissues, they become a little complex, as tissues become organs, they get a little complex, finally when organ systems are formed, they are highly complex from the organs, tissues and cells. Hope that answered your question.
