Concept:The taxonomic hierarchy is the fixed sequence of categories used to classify animals from the broadest group to the most specific group.Explanation:Organisms are grouped into taxa based on shared similarities and differences.The broadest taxon is $\mathrm{Kingdom}$, and the smallest taxon is $\mathrm{Species}$.The correct sequence followed for animal classification is:$\mathrm{Kingdom} \rightarrow \mathrm{Phylum} \rightarrow \mathrm{Class} \rightarrow \mathrm{Order} \rightarrow \mathrm{Family} \rightarrow \mathrm{Genus} \rightarrow \mathrm{Species}$.As we move from $\mathrm{Kingdom}$ to $\mathrm{Species}$, the number of common characters increases.Example: Human classification is $\mathrm{Animalia} \rightarrow \mathrm{Chordata} \rightarrow \mathrm{Mammalia} \rightarrow \mathrm{Primata} \rightarrow \mathrm{Hominidae} \rightarrow \mathrm{Homo} \rightarrow \mathrm{sapiens}$.Options A, B, and C are incorrect because their order does not follow this standard hierarchy.Option D matches the correct sequence.Answer:$\mathrm{Kingdom} \rightarrow \mathrm{Phylum} \rightarrow \mathrm{Class} \rightarrow \mathrm{Order} \rightarrow \mathrm{Family} \rightarrow \mathrm{Genus} \rightarrow \mathrm{Species}$ (Option D).
