C. Insertion of muscle
D. Fascia

Answer

To answer the question, "The site of attachment of a tendon to a fixed bone is called," we will analyze the options provided and determine the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding Tendons**:
- Tendons are fibrous connective tissues that attach muscles to bones. They play a crucial role in the movement of the skeletal system.

2. **Identifying the Terminology**:
- We need to identify the correct term that describes the attachment of a tendon to a fixed bone. The options given are:
- a) Origin of muscle
- b) Aponeurosis
- c) Insertion of muscle
- d) Fascia

3. **Evaluating Each Option**:
- **Option a: Origin of muscle**:
- The origin of a muscle refers to the point where the muscle attaches to a stationary bone. This is not specifically about tendons but rather about muscle attachment.
- **Option b: Aponeurosis**:
- An aponeurosis is a type of tendon that is flat and sheet-like, connecting muscles to the parts they move. It can also refer to the attachment of a tendon to a fixed bone.
- **Option c: Insertion of muscle**:
- The insertion of a muscle is the point where the muscle attaches to the bone that it moves. This is the opposite of the origin.
- **Option d: Fascia**:
- Fascia is a connective tissue that surrounds muscles and organs, but it is not specifically related to the attachment of tendons to bones.

4. **Conclusion**:
- After evaluating all the options, the correct answer is **b) Aponeurosis**. This term specifically refers to the site of attachment of a tendon to a fixed bone.

### Final Answer:
The site of attachment of a tendon to a fixed bone is called **Aponeurosis**.
