The fibres of elastic cartilage are  

Options

A. collagen & keratin
B. keratin & fibrin
C. fibrin & collagen
D. elastin & collagen

Answer

To answer the question about the fibers of elastic cartilage, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Elastic Cartilage**:
- Elastic cartilage is a type of connective tissue that provides flexibility and support. It is found in structures such as the ear and the epiglottis.

2. **Identifying the Fibers**:
- The main fibers present in elastic cartilage are elastin fibers, which give it its elastic properties.

3. **Collagen Presence**:
- In addition to elastin, elastic cartilage also contains collagen fibers. Collagen provides strength and structure to the cartilage.

4. **Eliminating Incorrect Options**:
- The options given were:
- Collagen and keratin
- Keratin and fibrin
- Fibrin and collagen
- Elastin and collagen
- Keratin is not a component of elastic cartilage, and neither is fibrin. Therefore, the options containing these fibers can be eliminated.

5. **Conclusion**:
- The only option that correctly identifies the fibers present in elastic cartilage is "elastin and collagen."

### Final Answer:
The fibers of elastic cartilage are **elastin and collagen**.
