Binomial Nomenclature means

The correct option is: one scientific name consisting of a generic name and a specific epithet.

Detailed Explanation:

1. Definition of Binomial Nomenclature:
Binomial nomenclature is a standardized, scientific system of naming living organisms. It was introduced and popularized by the Swedish botanist Carl Linnaeus to replace long, descriptive, and confusing common names with a unique, universally accepted system of identification.

2. The Two-Part Naming Structure:
The word "binomial" translates to "two names" or "two parts." Under this taxonomic naming system, every species is assigned a single scientific name that consists of two distinct components:
• Generic Name (Genus): The first word indicates the genus to which the organism belongs. The first letter of the generic name is always capitalized (e.g., Homo).
• Specific Epithet (Species): The second word identifies the specific species within the genus. It is written entirely in lowercase letters (e.g., sapiens).

3. Illustrative Example:
In the scientific name for humans, Homo sapiens:
• Homo represents the generic name.
• sapiens represents the specific epithet.

4. Conclusion:
This structure ensures that each organism has a single, unique, two-part scientific name, which directly corresponds to the option: one scientific name consisting of a generic name and a specific epithet.
