The correct option is C Mangifera indica
The system of providing a name with two components is called binomial nomenclature, as given by Carl Linnaeus. One of the main objectives of developing such a system was so that every organism would have the same standard name used anywhere across the world. Each name has two components - a generic name and a specific epithet. When typed, both the components of the name are italicised, with the first one capitalised as well. In the case of mango, "mangifera" is the generic name and "indica" is the specific epithet. Applying the above rules, it is typed as Mangifera indica.
