Options

A. Streptococci
B. Diplococci
C. Staphylococci
D. Pneumococci.

Answer

To determine which type of cocci appears as a bunch of grapes under a microscope, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Cocci**:
- Cocci are spherical bacteria and can be classified based on their arrangement.
- The main types include:
- **Staphylococci**: These cocci appear in clusters, resembling a bunch of grapes.
- **Diplococci**: These cocci appear in pairs.
- **Streptococci**: These cocci appear in chains.

2. **Analyze the Options**:
- **Staphylococci**: As mentioned, they cluster together, giving a grape-like appearance.
- **Diplococci**: They form pairs, not clusters.
- **Streptococci**: They form chains, which is different from the grape-like structure.
- **Pneumococci**: These are a type of streptococci and also do not form clusters.

3. **Identify the Correct Answer**:
- Since the question specifically asks for the type of cocci that appears as a bunch of grapes, the only option that fits this description is **Staphylococci**.

### Conclusion:
The correct answer is **Staphylococci**.
