B. (0) & (-)
C. (+) & (-)
D. (-) & (-)

Answer

### Step-by-Step Solution:

1. **Understanding the Concept of Ammensalism**:
- Ammensalism is a type of interaction between two species where one species is harmed while the other is unaffected.

2. **Identifying the Types of Interactions**:
- In ecological interactions, we often categorize them based on the effects they have on the species involved.
- The common types include:
- **Mutualism**: Both species benefit (positive-positive).
- **Commensalism**: One species benefits while the other is unaffected (positive-zero).
- **Predation**: One species benefits at the expense of another (positive-negative).
- **Competition**: Both species are harmed (negative-negative).
- **Ammensalism**: One species is harmed while the other is unaffected (negative-zero).

3. **Analyzing Ammensalism**:
- In ammensalism, we assign:
- Negative sign (-) to the species that is harmed.
- Zero sign (0) to the species that is unaffected.
- Therefore, the interaction can be represented as negative-zero.

4. **Conclusion**:
- Based on the definitions and analysis, ammensalism is a **negative-zero** type of interaction.

### Final Answer:
Ammensalism is a **negative-zero** type of interaction.
