B. Eubacteria are also called false bacteria
C. Phycomycetes are also called algal fungal
D. Cyanobacteria are also called blue-green algae

Answer

To determine which statement is wrong, let's analyze each one step by step.

### Step 1: Analyze the first statement
**Statement 1:** Golden Algae are also called Desmids.

- **Explanation:** Golden Algae, scientifically known as Chrysophyta, are not the same as Desmids. Desmids are a specific group of green algae belonging to the division Charophyta. Therefore, this statement is incorrect.

### Step 2: Analyze the second statement
**Statement 2:** Eubacteria are also called false bacteria.

- **Explanation:** Eubacteria are known as "true bacteria." The term "Eubacteria" itself means "true bacteria." Therefore, calling them "false bacteria" is incorrect. This statement is also wrong.

### Step 3: Analyze the third statement
**Statement 3:** Phycomycetes are algal fungal.

- **Explanation:** Phycomycetes is a group of fungi that includes some algae-like characteristics. They are often referred to as "algal fungi," which is a correct description.

### Step 4: Analyze the fourth statement
**Statement 4:** Cyanobacteria are also called blue-green algae.

- **Explanation:** Cyanobacteria are indeed referred to as blue-green algae due to their pigmentation, which includes chlorophyll and phycocyanin. This statement is correct.

### Conclusion
After analyzing all the statements, we find that both the first and second statements are incorrect. However, since the question asks for one wrong statement, the most clearly incorrect statement is:

**Final Answer:** The statement that "Eubacteria are also called false bacteria" is wrong (Statement 2).
