Which of the four names is 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 is correctly written according to the rules of binomial nomenclature, we will follow these steps:

### Step-by-Step Solution:

1. **Understand Binomial Nomenclature**:
- Binomial nomenclature is a system for naming organisms that consists of two parts: the genus name and the species name.

2. **Identify the Rules**:
- The **genus name** should start with a capital letter.
- The **species name** should start with a lowercase letter.
- Both names should be in Latinized form.
- If printed, the names should be in italics; if handwritten, they should be underlined.

3. **Examine the Options**:
- Look at each of the four names provided in the options.
- Check if the genus name is capitalized and if the species name is in lowercase.

4. **Evaluate Each Option**:
- **Option 1**: "Solenum mellongina" - The genus name is incorrectly written as "Solenum" (should be "Solanum") and the species name is incorrectly capitalized ("mellongina" should be "melongena"). This option is incorrect.
- **Option 2**: "Solanum melongena" - The genus name "Solanum" is correctly capitalized, and the species name "melongena" is correctly in lowercase. This option is correct.
- **Option 3**: "Solanum Melongena" - The genus name is correct, but the species name is incorrectly capitalized. This option is incorrect.
- **Option 4**: "solanum melongena" - The genus name is incorrectly written in lowercase. This option is incorrect.

5. **Conclusion**:
- The only option that follows all the rules of binomial nomenclature is **Option 2: "Solanum melongena"**.

### Final Answer:
- The correctly written name according to the rules of binomial nomenclature is **"Solanum melongena"**.
