In which group would there be the greatest similarity between members in terms of structure and function?
A. Genus.
B. Phylum.
C. Kingdom.
D. Species.
In the modern classification system, all living things are divided into 5 kingdoms. Each of these kingdoms is then further subdivided into phylums, classes, orders, families, geneses and species. The kingdoms are the broadest division while the species is the narrowest division, that is, organisms in the same kingdom may be very different from each other, but in the same species, organisms will be very similar.
