D. Universal with two specific names to each organism

Answer

### Step-by-Step Solution:

1. **Understanding Common Names**: Common names refer to the local or non-scientific names given to plants and animals. They are not standardized and can vary by region and language.

2. **Characteristics of Common Names**:
- Common names are non-specific, meaning they do not follow a universal naming system.
- They are often derived from local languages and can differ significantly from one region to another.

3. **Examples of Common Names**:
- For instance, the animal "lion" is known as:
- "Lion" in English
- "Léon" in French
- "Sher" in Hindi
- "León" in Spanish
- This illustrates how the same species can have different names in different languages.

4. **Need for Universal Names**: The variation in common names highlights the necessity for a universal naming system (scientific names) to avoid confusion and ensure clear communication across different regions and languages.

5. **Conclusion**: Based on the explanation, we can conclude that common names are non-scientific and non-specific names used locally for plants and animals.

### Final Answer:
Common names are non-scientific and non-specific names given to plants and animals, varying by region and language.
