In printed scientific names, only the _____ is capitalized.

(a) Class
(b) Species
(c) Genus
(d)Family

Correct Answer: (c) Genus

Explanation:

 In printed scientific names, only the genus name is capitalized.

Binomial means having two terms.  It is the biological system of naming the organisms in which the name is composed of a two-term naming system. It uses two different terms to name the species, plants, animals, and living organisms. It is also known as Binary Nomenclature.

The two terms consist of a generic epithet which is a genus (category) of that species, and a specific epithet that indicates the species itself.

This two-term naming system can also use some other different languages to create such scientific names. These scientific names are unique and help in identifying organisms anywhere in the world. 

Example: Rana Temporaria ( Common Frog). Here, rana is the generic name and temporaria is the specific name.
