Hint: The taxa are basically the hierarchical ranks used to represent various organisms. The correct sequence of groups that is universally accepted is ordered as Kingdom- Phylum- Class- Order- Family- Genus- Species.
Carolus Linnaeus is famously considered as the father/founder of modern taxonomy.

Complete answer: Taxonomy is the science of classifying organisms to construct internationally shared classification systems with each organism placed into more and more inclusive groupings.
Popularly, classifications of living organisms arise consistently with the need to understand organisms better.
Biologists have attempted to look at all living organisms with equal thoroughness and thus have devised a proper classification.
A proper classification provides the idea for a comparatively uniformed, and internationally understood nomenclature, thereby simplifying the retrieval of data.

So, the correct answer is option D. Genus.

Note: Taxonomy essentially sets up arrangements of the sorts of plants and animals in hierarchies of superior and subordinate groups.
Among biologists, Linnaeus' system of binomial nomenclature is internationally accepted.
