Genus represents

Concept:

• The term taxonomy was first introduced by A.P. de Candolle (1813) for the theory of plant classification. Later on, the term was accepted for zoological classification as well.
• Taxonomy can be defined as the study of principles, rules, and procedures of classification.
• All living organisms are arranged into different groups based on their similarities and dissimilarities in them.
• These groups are referred to as ranks or categories. All the categories together are referred to as Taxonomic Hierarchy.
• Taxon refers to a group of living organisms that represent a concrete unit of classification.
• Kingdom, Division, Class, Order, Family, Genus, and Species are the compulsory categories in a Taxonomic Hierarchy.
• Sub-order, sub-family, etc. are facultative categories that are used as per need.
• The sequence of compulsory categories in a taxonomic hierarchy is as follows:

Explanation:

Genus - 

• Genus is a taxonomic category that includes animals/ plants belonging to one or more related species.
• It includes species that share some common morphological characters but do not interbreed.
• In a taxonomic hierarchy, Genus lies between the ranks of Family and Species.
• Example:
• For example, potato and brinjal both belong to the genus Solanum.
• Lion (Panthera leo), leopard (P. pardus), and tiger (P. tigris) with several common features are all species of the genus Panthera.
• This genus differs from another genus Felis which includes cats.

So from the above-given explanation, the correct answer is option 3.
