Which one of the following is the correct taxonomic hierarchy?

The correct taxonomic hierarchy follows a descending order from the most general to the most specific level. According to the Linnaean system of biological classification, the standard sequence is Kingdom, Phylum, Class, Order, Family, Genus, and Species [2]. A Kingdom is the highest major rank, which is then subdivided into Phyla [1]. Each Phylum is further divided into Classes, which are subsequently partitioned into Orders [1]. Orders consist of related Families, and Families are composed of various Genera [1]. Finally, a Genus is made up of closely related Species, which represents the most basic unit of classification [1]. This hierarchical structure ensures that organisms are grouped based on shared characteristics and evolutionary relationships, moving from broad body plans at the phylum level to specific interbreeding populations at the species level [1].
