Question

consider the following statements:
(i) Genus comprises a group of related species
(ii) A taxon represents a taxonomic group of related genera
(iii) The family comprises a group of related genera
(iv) Taxonomic category class includes related order.
(a) (i), (ii) and (iv) are correct
(b) (ii) and (iv) are correct
(c) (i), (iii) and (iv) are correct
(d) (ii), (iii) and (iv) are correct

Answer 1

Hint: The order is preceded by taxonomy ranks-species, genus, family, order. This means that there are several species in each group, each family consists of several similar genera (plural of the group), and so on. A community of several species, not individual species, is Taxon.

Complete step by step answer:
A genus (plural genera) is a taxonomic rank used in biology for the biological classification of living organisms and fossils, as well as viruses. The genus falls above the species and below the family in the hierarchy of biological classification.
One of the eight main hierarchical taxonomic ranks in Linnaean taxonomy is the family (Latin: familia, plural familiae); it is divided between order and genus.
Order (Latin: ordo) is a taxonomic rank used and accepted by nomenclature codes in the classification of species. With order fitting in between family and class.
Taxonomy encompasses all the world's plants, animals, and microorganisms and is the science of naming, identifying, and classifying organisms.
So, the correct answer is ‘statement (i), (iii) and (iv) are correct’.

Additional information: All related species with similar origin or other important characteristics come under one genera. And all similar genera come under one family.The same way all similar families come under one order.
Seven key taxonomic ranks exist:
$\to$ kingdom, phylum or division, class, order, family, genus, species.

Note: Taxon, plural Taxa, any biological classification unit used in research, or taxonomy. Taxa are organized in a hierarchy from kingdom to subspecies, usually containing multiple lower-ranked taxa in a given taxon.
