"It would have DNA." is the one among the following characteristics that would be exhibited based on the concept of phylogeny, an organism that was ancestral to both the bacteria and eukaryota domains. The correct option among all the options that are given in the question is the third option or option "C". 

Answer: The correct answer is-

C. It would have DNA.

DNA is considered as the genetic material of life forms that carries genetic information in the form of nucleotide sequences. The genetic information is passed from one generation to the next generation.

Phylogeny can be described as the study of evolutionary history ( that is how different organism evolve from their ancestors) of different life forms and represents relationships among various species.

As we know that DNA is the genetic material that is transferred from one generation to the next generation, therefore  an organism that was ancestral to both the bacteria and eukaryota domains would also have the genetic material that is DNA.

Thus, option C) is the right answer.
