A. Humans and sperm whales are vertebrates and mammals, this implies that they have a common ancestor a long time ago, which makes them evolutionary related.
B. Conservation indicates that a sequence has been maintained by natural selection. This means that protein structure is not exactly the same but is quite similar.
Options C and D, contradict the above explanation, and they make no sense because sperm whales and humans share a common ancestor (mya).
