Answer:
B. Human beings all belong to one race.
Step-by-step explanation:
It is important to clarify that the distinction between human races is a social construct, this means it is a thing developed by human cultures to serve some purposes. In biology there is enough evidence to state that we all belong to one human race. It doesn't matter your geographic origin, ethnicity, color of skin, etc. We humans share a single phenotype, we have the same observable anatomical features and behaviour. In addition, your DNA, no matters were are you from, is 99.9 percent identical to another human's one.
