B. Coliphage
C. Bacteriophage
D. Zoophage.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of the virus that attacks blue-green algae. Blue-green algae are scientifically known as Cyanobacteria.

2. **Analyzing the Options**: The options provided are:
- A) Sinophage
- B) Coliphage
- C) Bacteriophage
- D) Zoophage

3. **Evaluating Each Option**:
- **Option A: Sinophage**: The term "Sinophage" includes "phage," which means virus. Sinophages specifically infect Cyanobacteria (blue-green algae). Therefore, this option is likely correct.
- **Option B: Coliphage**: "Coliphage" refers to viruses that infect coliform bacteria, such as E. coli. This does not relate to blue-green algae, so this option is incorrect.
- **Option C: Bacteriophage**: Bacteriophages are viruses that infect bacteria in general. Since blue-green algae are not classified as bacteria, this option is also incorrect.
- **Option D: Zoophage**: "Zoophage" refers to viruses that consume animal matter. This does not pertain to blue-green algae, making this option incorrect as well.

4. **Conclusion**: The only option that correctly identifies the virus that attacks blue-green algae is **Option A: Sinophage**.

5. **Final Answer**: The virus attacking blue-green algae is known as **Sinophage**.
