A homonym is

Options

A. Two or more names for the same taxon
B. Species name repeats the generic name
C. Identical name of two different species
D. Name given to a taxon in local language

Answer

To solve the question "A homonym is:", we need to analyze the options provided and understand the definition of a homonym in the context of biological nomenclature.

### Step-by-Step Solution:

1. **Understanding the Term "Homonym":**
- A homonym in biological terms refers to a situation where two different taxa (species or groups) are given the same name. This can lead to confusion in scientific communication.

2. **Analyzing the Options:**
- **Option A:** "Two or more names for the same taxon" - This describes a synonym, not a homonym.
- **Option B:** "Species name repeats the generic name" - This is a description of a specific naming convention, not a homonym.
- **Option C:** "Identical name for two different species" - This accurately describes a homonym, as it refers to different taxa sharing the same name.
- **Option D:** "Names given to a taxon in local language" - This does not relate to the concept of homonyms in scientific nomenclature.

3. **Identifying the Correct Answer:**
- Based on the definitions and analysis, the correct answer is **Option C: Identical name for two different species**.

4. **Explanation of Terms:**
- In biological nomenclature, the term "senior homonym" refers to the first published name that is considered valid, while "junior homonym" refers to subsequent names that must be replaced to avoid confusion.

### Final Answer:
The correct answer is **Option C: Identical name for two different species**.
