**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term used to describe the symbiotic relationship between fungi and algae.

2. **Identifying the Symbiotic Association**: The specific term that describes the symbiotic relationship between fungi and algae is "lichen."

3. **Defining Lichen**: Lichens are formed from the mutualistic association of two different organisms: a fungus (mycobiont) and an alga (phycobiont).

- The option stating both A and B is incorrect since only A (lichen) is correct.

6. **Conclusion**: Therefore, the correct answer to the question is "lichen."

**Final Answer**: The symbiotic association of fungi and algae is called **lichen**.
