D. Fascia

Answer

To answer the question, "A collagenous connective tissue layer that holds the muscle bundles together is?" we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Muscle Structure**:
- Muscle cells are organized into bundles, which are essential for the proper functioning of muscles. Each bundle consists of multiple muscle fibers.

2. **Role of Connective Tissue**:
- Connective tissues play a crucial role in providing support and structure to various tissues in the body. They help in holding different components together.

3. **Identifying the Specific Connective Tissue**:
- The connective tissue that specifically surrounds and holds muscle bundles together is made up of collagen, a protein that provides strength and elasticity.

4. **Naming the Connective Tissue Layer**:
- This specific layer of connective tissue that encases muscle bundles is known as "fascia."

5. **Functions of Fascia**:
- Besides holding muscle bundles together, fascia also supports organs, blood vessels, bones, and nerve fibers, ensuring that all these structures remain intact and function properly.

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

### Final Answer:
