A group of similar organisms which are genetically distinct and reproductively isolated, is called a/an-

Correct option is C

The correct answer is (c) Species.
In biological classification, a species is the basic unit of classification and a taxonomic rank. A species is defined as a group of similar organisms that can interbreed and produce fertile offspring. Members of the same species share common characteristics and are genetically similar. Importantly, they are reproductively isolated from other groups, meaning they do not breed with organisms outside their species under natural conditions. This reproductive isolation is crucial in maintaining the genetic distinctness of the species.
Additional Information:
· Class : This is a higher taxonomic rank that includes multiple orders. For example, Mammalia is a class that includes all mammals.
· Order : This is a taxonomic rank below the class and above the family. An example of an order is Carnivora, which includes families like Felidae (cats) and Canidae (dogs).
· Family : This rank is below the order and above the genus. It groups together genera that share a set of similar characteristics. For example, the family Felidae includes genera like Panthera (lions, tigers) and Felis (domestic cats).
