Which one is a incorrect nomenclature ?

Options

A. Felis domesticus
B. Felis domestica
C. mangifera indicus
D. Tamarindus indica

Answer

To determine which nomenclature is incorrect, we need to understand the rules of binomial nomenclature established by Carl Linnaeus. Binomial nomenclature consists of two parts: the genus name and the species name. The genus name is always capitalized, while the species name is written in lowercase. Both names should be italicized or underlined when written.

Let's analyze the options provided:

1. **Felis domesticus**:
- Genus: Felis (correctly capitalized)
- Species: domesticus (correctly in lowercase)
- This nomenclature is correct.

2. **Felis domestica**:
- Genus: Felis (correctly capitalized)
- Species: domestica (correctly in lowercase)
- This nomenclature is also correct.

3. **Mangifera indica**:
- Genus: Mangifera (should be capitalized)
- Species: indica (correctly in lowercase)
- However, the option is written as "Mangyphaera indica," which is incorrect because "Mangyphaera" is a misspelling of "Mangifera."
- This nomenclature is incorrect.

4. **Tamarindus indica**:
- Genus: Tamarindus (correctly capitalized)
- Species: indica (correctly in lowercase)
- This nomenclature is correct.

Based on the analysis, the incorrect nomenclature is option number 3, "Mangifera indica," due to the misspelling of the genus name.

### Final Answer:
The incorrect nomenclature is **option number 3: Mangifera indica** (due to misspelling).
