Which of the following biological name is wrongly written

The correct answer is Mangifera Indica.

To understand why this biological name is wrongly written, let us look at the rules of binomial nomenclature established by Carl Linnaeus:
1. A scientific/biological name consists of two parts: the genus name (generic name) and the species name (specific epithet).
2. The genus name must always start with a capital letter (e.g., Mangifera, Triticum, Felis, Apis).
3. The species name must always start with a lowercase letter (e.g., aestivum, domesticus, indica).
4. When printed, scientific names are written in italics. When handwritten, they are underlined separately.

Looking at the given options:
- Triticum aestivum (Wheat) follows the rules correctly.
- Felis domesticus (Domestic Cat) follows the rules correctly.
- Apis indica (Indian Honey Bee) follows the rules correctly.
- Mangifera Indica (Mango) is written incorrectly because the species name "Indica" starts with a capital letter "I" instead of a lowercase "i". The correct representation should be Mangifera indica.
