Answer 2

D) Of the four organisms, the calf and human are most closely related.

Step-by-step explanation:

According to biogenetic law, stages of embryological development of an organism recapitulates its evolutionary history. The shared characters are exhibited by early embryological stages of various species while the derived features appear in later stages. Since the calf and the human embryo resemble during later stages of embryological development, they are most closely related to each other.
