Question

Hierarchy of categories of Carolus Linnaeus had categories except

• A. Genus and species
• B. Order and class
• C. Kingdom and class
• D. Phylum and family

Answer 1

The correct option is D Phylum and family

In his book Systema Naturae, Linnaeus proposed that there were three broad groups, called kingdoms. These kingdoms were animals, plants, and minerals. He divided each of these kingdoms into classes. Classes were divided into orders. These were further divided into genera (genus is singular) and then species.

Today we have excluded minerals and added few more categories.The classification broadest level of life is now a domain. All living things fit into only three domains: Archaea, Bacteria, and Eukarya. Within each of these domains there are kingdoms. For example, Eukarya includes the kingdoms Animalia, Fungi, Plantae, and more. Each kingdom contains phyla (singular is phylum), followed by class, order, family, genus, and species.

So, the correct answer is 'Phylum and family'.
