The best assumption based on the information provided is:

B The calf, human, and tortoise are more closely related to one another than the fish.

This conclusion can be drawn because the early similarities in the embryos suggest a common ancestry, but the significant differences in the fish's development indicate that it is less closely related to the other three species (calf, human, and tortoise) which share more similarities in their later embryonic stages.
