Question: 169: In the taxonomic categories which hierarchical arrangement in ascending order is correct in case of animals?
(1) Kingdom, Order, Class, Phylum, Family, Genus, Species
(2) Kingdom, Order, Phylum, Class, Family, Genus, Species
(3) Kingdom, Phylum, Class, Order, Family, Genus, Species
(4) Kingdom, Class, Phylum, Family, Order, Genus, Species
Answer: Option (3)
Explanation:
In biological classification, organisms are arranged into taxonomic categories based on similarities and differences.
The correct hierarchical order from higher category to lower category in animals is: Kingdom → Phylum → Class → Order → Family → Genus → Species.
Here, Kingdom is the broadest category containing maximum diversity, while Species is the most specific category representing closely related organisms.
Although the question mentions the term “ascending,” the correct logical interpretation is descending order from higher to lower taxonomic rank.
Option (3) correctly represents this standard taxonomic hierarchy used in animal classification.
