The correct answer is "They all share at least 50% of the same DNA arrangement".
Explanation:
DNA analysis have allowed to establish phylogenetic trees with reliable information about the evolutionary relationship that species have. In this example Animal A and Animal B share 95% of their DNA sequences, while Animal A and Animal C share 50%. Even though Animal B and Animal C relationship is not established, it is sure to state that all animals share at least 50% of the same DNA arrangement since Animal A and Animal B are almost identical. This support the idea that life changed over time, where it is likely that all animals share a common ancestor that eventually diverged in the three animals at which Animal C is the most divergent.
