What is correct

Options

A. Apis indica
B. trypanosoma gambiense
C. Ficus Bengalensis
D. Mangifera indica

Explanation

### Step-by-Step Solution:

1. **Understanding Binomial Nomenclature**:
- The scientific naming system, known as binomial nomenclature, consists of two parts: the genus name and the species name. The genus name is always capitalized, while the species name starts with a lowercase letter.

2. **Analyzing Each Option**:
- **Option 1: Apis indica**
- This is the name of the Indian honey bee. The genus name "Apis" is capitalized and the species name "indica" is in lowercase. This is correct.
- **Option 2: Apis serena indica**
- Here, "Apis" is the genus and "serena" is the species name, while "indica" is a subspecies. The genus name is capitalized and the species name is in lowercase. This is also correct.
- **Option 3: Trypanosoma gambiense**
- This protozoan causes sleeping sickness. However, the genus name "Trypanosoma" should be capitalized. Since it is written as "tropanosoma," this is incorrect.
- **Option 4: Ficus benghalensis**
- This is the scientific name for the banyan tree. The genus name "Ficus" is correct, but the species name "benghalensis" should start with a lowercase letter. However, it is written with a lowercase letter here, which is correct.
- **Option 5: Mangifera indica**
- This is the scientific name for the mango. The genus name "Mangifera" is capitalized and the species name "indica" is in lowercase. This is correct.

3. **Conclusion**:
- The correct scientific names according to the rules of binomial nomenclature are:
- Apis indica (correct)
- Apis serena indica (correct)
- Trypanosoma gambiense (incorrect due to capitalization)
- Ficus benghalensis (correct)
- Mangifera indica (correct)

4. **Identifying the Correct Option**:
- The only option that is entirely correct in terms of scientific naming conventions is **Mangifera indica**.

### Final Answer:
The correct scientific name is **Mangifera indica**.
