Complete answer:
To answer this question, first, we need to know about the binomial system of classification. Binomial nomenclature is the biological system of naming the organisms in which the name is composed of two terms, where the first term indicates the genus and the second term indicates the species of the organism.
Now, let us find the solution from the option.
In the binomial system of classification, every species is given in a name with two parts. The first part represents a genus and the second part is a specific epithet. Together these two are called species. Oryza sativa is the binomial name of rice.
Eg. Oryza sativa where Oryza is genus and sativa is a specific epithet and these two together represent species.

Thus, the correct option is C. i.e. Specific epithet.

Note:The system of binomial nomenclature was introduced by Carl Linnaeus. Multiple local names make it extremely difficult to identify an organism globally and keep a track of the number of species. Thus, it creates a lot of confusion. To get rid of this confusion, a standard protocol came up. According to it, each and every organism would have one scientific name which would be used by everyone to identify an organism.
