Options

A. Mutualism
B. Parasitism
C. Commensalism
D. Predation

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question:** The question asks for a type of association between two organisms where one benefits without affecting the other.

2. **Identifying the Options:** The options provided are:
- Mutualism
- Parasitism
- Commensalism
- Predation

3. **Analyzing Each Option:**
- **Mutualism:** This is a symbiotic relationship where both organisms benefit from the association. Therefore, this option does not fit the criteria of the question.
- **Parasitism:** In this relationship, one organism (the parasite) benefits at the expense of the other (the host). This option also does not fit the criteria since one organism is harmed.
- **Commensalism:** This is the correct option. In commensalism, one organism benefits while the other is neither helped nor harmed. An example is the sucker fish that attaches to a shark and feeds on leftovers.
- **Predation:** In predation, one organism kills and consumes another, which does not meet the criteria of the question.

4. **Conclusion:** The correct answer to the question is **commensalism**.
