What is correct

Options

A. APIS INDICA
B. trypansoma gambiense
C. Ficus Bengalensis
D. Mangifera indica

Answer

To determine which of the given options correctly follows the rules of binomial nomenclature, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Binomial Nomenclature**:
- Binomial nomenclature is a formal system of naming species. Each species is given a name composed of two parts: the genus name (which is capitalized) and the species epithet (which is in lowercase). Both parts should be italicized or underlined.

2. **Analyzing Each Option**:
- **Option A: Apis indica**
- The genus name "Apis" is correctly capitalized, but "indica" is in lowercase. However, if it is written in all uppercase letters, it is incorrect. Therefore, this option is **incorrect**.

- **Option B: Trypanosoma gambenes**
- The genus name "Trypanosoma" should start with an uppercase letter, but if it is written in all lowercase, it is incorrect. Therefore, this option is **incorrect**.

- **Option C: Ficus bengalis**
- The genus name "Ficus" is correctly capitalized, but "bengalis" should be in lowercase. If "bengalis" is capitalized, it is incorrect. Therefore, this option is **incorrect**.

- **Option D: Mangifera indica**
- The genus name "Mangifera" is correctly capitalized, and "indica" is in lowercase. This option follows the rules of binomial nomenclature correctly. Therefore, this option is **correct**.

3. **Conclusion**:
- The correct answer is **Option D: Mangifera indica**.
