Explanation:   b) Linnaeus

Swedish naturalist and explorer Carolus Linnaeus was the first to frame principles for defining natural genera and species of organisms and to create a uniform system for naming them.

The classification will come to the genus (plural genera) and species. These are the names that are most commonly used to describe an organism.

An example within the primate family is the genus Homo for all human species .
