A the answer is A) A two word system for naming organisms by using the genus and species.

The classifications of living organisms (taxonomy) uses the following categories to distinguish one creature from another: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. Binomial nomenclature refers to the Genus and Species of this classification, which is often used to identify an organism without having to name its entire classification. This method is more effective than using the common name of the organism, which can differ from region to region.
