### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Predation**: This is an interaction where one organism (the predator) benefits by feeding on another organism (the prey), which is harmed or killed in the process.
- **Allelopathy**: This refers to a biological phenomenon where one organism produces chemicals that can affect the growth or survival of another organism, but it does not specifically imply that one is harmed while the other benefits.
- **Symbiosis**: This is a close association between two organisms where both partners benefit from the interaction.

- The question states that one partner is benefitted (the strong partner) and the other is damaged (the weak partner).

3. **Identifying the Correct Answer**:
- Based on the definitions, predation is the only interaction where one organism benefits (the predator) and the other is harmed (the prey). Therefore, the correct answer to the question is **predation**.
