Question

A. Kingdom, genus, class, phylum, and division
B. Phylum, kingdom, genus, species and class
C. Kingdom, phylum, class ,genus and species
D. Phylum, division, family, genus and class

Answer 1

Hint: The count of animal and plant species is very large, it is impossible to know them individually by their names or to mention them in literature. This requires dividing them into categories and taxa of different degrees. Then arrange the categories and taxa in ascending order so that the higher category contains one or more lower categories and the higher taxa one or more lower taxa.

Complete answer:
Category: Animal groups are taxa. Each taxon is assigned to a certain level in the hierarchy. Categories indicate ranks or levels in a hierarchical classification. It is a class whose members are all taxa which have been assigned a certain rank. One category can be higher or lower than another so we can talk about a higher category.
All categories are arranged in ascending order and form a taxonomic hierarchy. Seven mandatory categories are used in the taxonomic study of all known organisms: Kingdom, Division (for plants) or Type (for animals), Class, Order, Family, Genus and Species. These broad categories are further broken down into subcategories, with super- sub- or infra-prefixes being used to allow for better and more scientific placement of taxa. As we move from species to kingdom, the number of correlated signs continues to decline.

So the correct option is (A).

Note: Linnaeus first introduced a hierarchical classification system. Two categories were not included in the classification;. phylum and families. In the taxonomic hierarchy, species is the basic unit of classification and lowest category, while kingdom is the highest category.
Also, an eighth category called domain (synonymous with super kingdoms) is sometimes used above the kingdom level. Recently, a new category of "tribe" was added between genus and subfamily, while "parared" was added between parades and superfamilies. The aim of the introduction of Parvorder and Stamm is to provide a constant time gradient between classification levels.
