The correct option is C Linnaeus
Linnaeus not only laid the foundation of taxonomy but all introduced binomial nomenclature. According to this, the scientific name consists of two parts, the first is the name of the 'genus' called 'generic epithet' and the second is called the 'specific epithet' that identifies the particular 'species' within the genus.
The names are written in italic, generic name begins with capital letter and specific name begins with small letter,
e.g. Brassica indicia (sarsaun in Hindi).
