which one is mismatched w.r.t. population interactions.

Options

A. +(species A), +(species B), Mutualism(name of interaction)
B. -(species A), -(species B), competition (name of interaction)
C. 0(species A), +(species B), Amensalism(name of interaction)
D. +(species A), 0(species B), Commensalism( name of interaction)

Answer

To determine which option is mismatched with respect to population interactions, we need to analyze the definitions of the interactions provided in the question.

### Step-by-Step Solution:

1. **Identify the Types of Population Interactions**:
- Mutualism: Both species benefit.
- Competition: Both species lose.
- Commensalism: One species benefits while the other is neither helped nor harmed.
- Parasitism: One species benefits at the expense of the other.

2. **Analyze Each Option**:
- **Option A**: Both species are benefiting. This is correctly identified as mutualism. **(Correct)**
- **Option B**: Both species are losing. This is correctly identified as competition. **(Correct)**
- **Option C**: One species is getting a benefit, and the other is neutral. This is incorrectly labeled as commensalism. In commensalism, one species benefits while the other is not significantly affected, but it is not accurate to say one is getting a benefit and the other is neutral. This description does not fit any of the standard definitions. **(Mismatched)**
- **Option D**: This option is not provided in the transcript, but if it follows the definitions, it should be correct.

3. **Conclusion**: The mismatched option is **Option C**, as it incorrectly describes the interaction.

### Final Answer:
The mismatched option with respect to population interactions is **Option C**.
