Answer:

A. The two proteins are very likely related evolutionarily.

B. The differences in the sequences in many instances represent a conservative change (such as L for I).

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).
