Which of the 4 names are correctly written as per rules of binomial nomenclature?

Options

A. SOLANUM MELONGENA
B. Solanum melongena
C. Solanum Melongena
D. solanum melongena

Answer

To determine which of the four names are correctly written according to the rules of binomial nomenclature, we will follow these steps:

### Step 1: Understand Binomial Nomenclature
- Binomial nomenclature is a two-part naming system for organisms, introduced by Carl Linnaeus in 1751.
- The first part of the name is the **genus**, and the second part is the **specific epithet** (species).

### Step 2: Rules for Writing Names
- The **genus name** should always start with a **capital letter**.
- The **specific epithet** should always start with a **small letter**.
- Both names should be italicized when written.

### Step 3: Analyze Each Option
1. **Option 1**: Both names are in capital letters.
- **Analysis**: This is incorrect because the specific epithet should be in lowercase.

2. **Option 2**: Solanum Melangina
- **Analysis**: "Solanum" (genus) starts with a capital letter, and "Melangina" (species) starts with a lowercase letter. This is correct.

3. **Option 3**: Both names are in capital letters.
- **Analysis**: This is incorrect for the same reason as Option 1.

4. **Option 4**: The genus is written in lowercase.
- **Analysis**: This is incorrect because the genus name must start with a capital letter.

### Conclusion
- The only correctly written name according to the rules of binomial nomenclature is **Option 2: Solanum Melangina**.
