Answer:
D
Explanation:
D. There is no way to calculate the biological answer for this question.
The concept of biological races in humans is highly debated and controversial. While there are genetic variations among human populations, the idea of distinct, separate biological races is not supported by modern scientific consensus. Human genetic variation is continuous and does not neatly align with traditional racial categories. Moreover, genetic differences between populations are generally small compared to the genetic variation within populations. Therefore, it is not possible to determine a specific number of biologically distinct, separate races among humans alive today.
