The correct answer is - C. genus and species.
The final scientific name of an animal represents two things, its genus, and its species.
The first name is the genus of the animal, in this case we have Canus. The second name is the species of the animal, in this case nipponicus.
All living organisms are classified in a same manner: kingdom, phylum, class, order, family, genus, species.
Since the name Canus reminds me a lot of Canis, I will take the wolf as an example:
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Carnivora
Family: Canidae
Genus: Canis
Species: C. Lupus
