The scientific binomial name of a species is Canis vulpis. Which of the following is true? A. the species belongs in the family Canis. B. the species belongs in the genus vulpis. C. the species belongs in the genus Canis. D. the species belongs in the family vulpis.

To determine which option is correct, we need to understand how the scientific binomial name is structured.

The scientific binomial name consists of two parts: the genus name and the species name. In this case, "Canis" is the genus name and "vulpis" is the species name. The genus name is always capitalized, while the species name is not.

Now, let's evaluate the given options:

A. The species belongs in the family Canis.
This option is incorrect because the scientific binomial name does not indicate the family of the species. It only specifies the genus and species.

B. The species belongs in the genus vulpis.
This option is incorrect because "vulpis" is actually the species name, not the genus. The genus name is "Canis".

C. The species belongs in the genus Canis.
This option is correct. The genus name in the scientific binomial name is "Canis", so the species does indeed belong in the genus Canis.

D. The species belongs in the family vulpis.
This option is incorrect for the same reason as option A. The scientific binomial name does not indicate the family of the species.

In summary, the correct statement is:
C. The species belongs in the genus Canis.
