Answer 1

Hint:To answer this question, recall the botanical names of the given species. The genus as well as the species named according to the binomial nomenclature.

Complete answer:
Binomial nomenclature is a legal system of naming organisms by giving it a name composed of two parts, both present in Latin grammatical forms, they can even be based on words from other languages. The name thus formed is called a binomial name or a scientific name.
The first part of the name has to be the generic name, it identifies the genus of the species, while the second part is the specific epithet which identifies the species from the genus. For example, humans belong to the genus Homo and the species is sapiens, forming Homo sapiens. This system was proposed by Carl Linnaeus, but Gaspard Bauhin introduced it in his book named Pinax theatri botanici. The use of binomial nomenclature is now governed by several internationally agreed rules for coding, the two most important organizations are the International Code of Zoological Nomenclature (ICZN) which looks after naming of animals and the International Code of Nomenclature for algae, fungi, and plants (ICNafp). The name of jowar is Sorghum vulgare where Sorghum is the genus and vulgare is its species. Similarly, the botanical name of rice is Oryza sativa where the first name is genus and the second is its species.

The correct answer is- C. Sorghum vulgare and Oryza sativa.

Note: In binomial nomenclature, the first letter of genus is always written in capital writing, while the species name is written in lower case. In a normal text, both words are written in Italic font and underlined.
