C. Mycobiont
D. Probiont

Answer

To solve the question about the fungal partner in a lichen relationship, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Lichen**:
- Lichens are a mutualistic relationship between two organisms: a fungus and an alga (or cyanobacterium).

2. **Identifying the Partners**:
- In this relationship, the alga is the autotrophic partner, which means it can produce its own food through photosynthesis. The alga contains chlorophyll, which facilitates this process.

3. **Role of the Alga**:
- The alga provides food to the fungal partner, which is heterotrophic and cannot produce its own food.

4. **Role of the Fungus**:
- The fungal partner provides shelter and protection to the alga, creating a symbiotic relationship where both organisms benefit.

5. **Terminology**:
- The alga is referred to as "phycobiont" (where "phyco" indicates algae), while the fungal partner is referred to as "mycobiont" (where "myco" indicates fungi).

6. **Conclusion**:
- Therefore, in the context of the question, the fungal partner in a lichen relationship is called **mycobiont**.

### Final Answer:
The fungal partner in a lichen relationship is called **mycobiont**.
