Options

A. mycorrhiza
B. root
C. lichens
D. BGA

Explanation

To solve the question regarding the association between mycobiont and phycobiont, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Mycobiont**: This term refers to the fungal component of a symbiotic relationship.
- **Phycobiont**: This term refers to the algal component of a symbiotic relationship.

2. **Identifying the Association**:
- The question asks about the association between mycobiont and phycobiont. This association is typically found in a specific type of organism.

3. **Analyzing the Options**:
- **Mycorrhizae**: This is a symbiotic association between fungi and the roots of higher plants, but it does not involve algae.
- **Root**: This option does not represent a symbiotic association involving both fungi and algae.
- **Lichens**: This is a well-known example of a symbiotic relationship between fungi (mycobiont) and algae (phycobiont).
- **BGA (Blue-Green Algae)**: While this refers to a type of algae, it does not represent a symbiotic association with fungi.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Lichens**, as they are the organisms that exhibit the permanent symbiotic association between mycobiont (fungus) and phycobiont (alga).

### Final Answer:
The association between mycobiont and phycobiont is found in **Lichens**.
