B. Class
C. Species
D. Kingdom
E. Genus

Answer 1

Hint:- Scientific names are the standard names that are given to organisms to identify them and each scientific name is specific only to one organism. Scientific names are given on the basis that from where the organism originates and also according to the characteristics features of organisms.

Complete Answer:- All biologists follow internationally agreed and accepted codes of rules or principles while assigning scientific name to known or newly discovered organisms. Binomial nomenclature for scientific naming of organisms was developed by Carolus Linnaeus. This system provides distinct and proper scientific names to a variety of organisms. Each name has two parts, i.e., the first part comprises its generic name, while the second part is the specific epithet. This naming system which uses two-word format is universally accepted and used, as it is more convenient to understand and follow.
Rules of Binomial Nomenclature: Some universal rules of Nomenclature framed under codes of ICZN. ICBN, etc. are as follows:
Biological names are generally taken from Latin language irrespective of their origin. New names are now derived either from Latin language or Latinised.
Each organism is given only one name consisting of two words. The first word in a biological name represents its genus while the second component denotes the specific epithet.
The scientific name is usually printed in italics and in case of handwritten underlined separately to indicate their Latin origin
The first word denoting and indicating genus starts with a capital letter, while the specific epithet starts with a small letter.
The name of the author or discoverer is written after a specific epithet in abbreviated form. For example, Mangifera indica Linn. It indicates that this species was first described by Linnaeus.
All the three words (generic name, species epithet and author citation) collectively form a binomial epithet.
So according to the above discussion the genus name starts with a capital letter.

Our required option is e that is genus

Note:- Principle of priority is the most important of all the rules of ICBN. If the first name given to the organism is valid in terms of rules), that will be considered at the first preference. Any other valid name given after that will be considered as a synonym. No names are recognised prior to those used by Linnaeus in 1758 in the 10th edition of Systema Naturae for animals and 1753 for plants
