Hint:Taxonomic hierarchy refers to the set of groups in increasing or decreasing order. The Kingdom is of the highest rank preceded by division, class, order, family, genus, and species.
A taxon is a group of organisms classified as a unit. Human taxonomy is the grouping of the human race in the zoological taxonomy. Each of these hierarchical levels is called a taxonomic category or rank. The Kingdom is the highest classification category and is split into subgroups at different ranks. There are five kingdoms in which living beings are classified, including Animalia, Plantae, Fungi, Protista and Monera. The phylum is the next level of grouping that is more unique to the empire. The kingdom of Animalia has 35 phyla. Few are Porifera, Chordata, Arthropoda, etc. The class was the most general rank in the taxonomic hierarchy before phyla were added. Kingdom Animalia comprises 108 groups, including mammals, reptiles, insects, etc.
The Kingdom of Animalia is all species. Of the five kingdoms, the main kingdom is the animal kingdom. Animals are multicellular eukaryotic. Like plants, though, they do not have chlorophyll or a cell wall. The members of the animal kingdom thus show a heterotrophic mode of nutrition. Phylum Chordata is bilaterally symmetrical and triploblastic. They have an organ-system classification level. They possess a notochord and a nerve cord and they have a closed-loop circulatory system. Animals belonging to the Mammalia class are addressed to as mammals. Mammals are among the most specialised animals in the animal world known as vertebrates.
The correct answer is ‘Human beings belong to the kingdom Animalia, Phylum Chordata and Class Mammalia’.
Hence the correct answer is option ‘C’.
Note:The term "taxonomy" originated from the Greek word "taxis," implying arrangement or division, and "nomos," means process. Taxonomy is a biology branch that means the process of classifying different species on the planet.
