Answer:
The correct answer would be D. species.
Natural taxon refers to the group of organisms which exists in nature as a consequence of evolution.
In Linnaeus's system, the only natural taxon is "species".
Species refers to the group of organisms in which two organisms of opposite or appropriate genders can produce a viable offspring.
In meiosis one, homologous chromosomes only separate resulting in two cells. In meiosis II, the cells divide further, separating sister chromatids and resulting in four cells. So the cells are just even smaller with less chromosomes in each one.
