Explanation

The system of bionomial nomenclature was developed by Linnaeus. There were certain rules which were set up for writing the scientific names. They are as follows:

1. Each organism is given only one name consisting of two words- generic and specific.
2. The scientific name is printed in italics. It is underlined in handwritten description. 
The generic name is written first. It is followed by specific name and the name of discoverer in full or abbreviation. 
4. The name of the author is written in Roman script.
5. The original names were taken from Latin and Greek languages. New names are derived from latin language as Latin is a dead language and therefore it will not change in form or spelling with the passage of time. 
Thus, the correct answer is option B.
