D)Division

Answer 1

In biological classification, different levels of groups are organized on the bases of their characteristics of different animals, plants, bacteria, fungi and protists. Levels of organization are called taxon or taxonomic rank. These are given specific naming patterns for easy study and identification.

Complete answer:
All the animals and plants present on this planet Earth are classified on the basis of their physical and biological characters. This is known as biological classification. Examples of these taxonomic ranks are species, genus, order, class, kingdom, etc.
Biological classification ranks are in order: Life – Domain – Kingdom – Phylum – Class – Order – Family – Genus – Species.

In zoology, this classification is also used for study and used for advancement in the studies. With the advancement of scientific technologies and techniques, this biological classification is also getting better in databases and documentation.

Family is the taxonomic rank that comes in-between order and genus. And family can be divided into subfamilies, which can act as intermediate ranks between the taxonomic ranks of family and genus. The family names are generally written in Latin for example: Walnut trees belong to Juglandaceae and commonly referred to as being the “walnut family”.

Hence, the correct answer is option (A)

Note: In fungal, algal families are given the suffix “aceae”. Different families can be used for evolutionary, palaeontological and genetic studies as they are more stable than lower taxonomic levels such as genus and species.
