D. Sumbiont

Answer

To solve the question regarding Loranthus, we will analyze the options provided and determine the correct classification based on its characteristics and behavior.

### Step-by-Step Solution:

1. **Understanding Loranthus**:
- Loranthus is a type of plant that grows on the stems of other trees. It is important to note that it does not grow in the soil but rather attaches itself to a host plant.

**Hint**: Consider where Loranthus grows and how it interacts with its environment.

2. **Nutrient Absorption**:
- Loranthus absorbs water and nutrients directly from the host plant. This means that it relies on the host for its sustenance.

**Hint**: Think about the implications of one organism taking resources from another.

3. **Effect on Host Plant**:
- The relationship between Loranthus and the host plant is detrimental to the host. The host plant suffers because it loses water and nutrients to Loranthus.

**Hint**: Reflect on the impact of one organism benefiting at the expense of another.

4. **Identifying the Type of Relationship**:
- Given that Loranthus benefits while the host plant is harmed, this relationship is classified as parasitism. In parasitism, one organism (the parasite) benefits, and the other organism (the host) is harmed.

**Hint**: Recall the definitions of commensalism, epiphytism, and symbiosis to differentiate them from parasitism.

5. **Evaluating the Options**:
- (a) Commensal: One benefits, the other is neither helped nor harmed. Not applicable here.
- (b) Epiphyte: Lives on another plant but does not absorb nutrients. Not applicable here.
- (c) Parasite: One benefits at the expense of the other. This fits Loranthus.
- (d) Symbiont: Both organisms benefit. Not applicable here.

6. **Conclusion**:
- The correct answer is (c) Parasite, as Loranthus benefits from the host plant while harming it.

### Final Answer:
(c) Parasite
