Definition of taxonomic hierarchy and category :
Taxonomic hierarchy is the arrangement of taxonomic categories in an ascending or descending order, such that the number of similar characters among the members falling in a particular category decreases from lowest rank to highest rank. Taxonomic category is an abstract term that represents distinct levels present in the taxonomic hierarchy.

Sequence of taxonomic categories :
Taxonomic categories can be sequenced in an ascending order or descending order. The seven obligate categories in the taxonomic hierarchy are kingdom, phylum/division, class, order, family, genus and species.


Correct sequence :
The correct sequences are $a)$ and $c)$.

$a)$ Species $\to$ Order $\to$ Phylum $\to$ Kingdom

$c)$ Species $\to$ Genus $\to$ Order $\to$ Phylum

This is because they are in accordance with the taxonomic hierarchy.
Option $b)$ is incorrect because it does not follow the taxonomic hierarchy.
