Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Nomenclature is application of correct name to plants and taxonomic rank under the rule as drawn by ICBN (International Code for Botanical Nomenclature); option A is incorrect and B is correct. Scientific names formulated in Latin language are preferred over those in vernacular languages due to restricted use and application of these names in one or two languages and non-availability of vernacular names for all known plant species; this makes option C incorrect. Scientific names are not formulated in English but in Latin because latter one is a dead language and the meanings of words are not prone to changes as is the case with English; this makes option D incorrect. Thus, the correct answer is option B.
