D. Coir

Answer

To determine which plant has the longest fibers among the given options, we can analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding the Options**:
- We have four options: Jute, Cotton, Sun Hemp, and Coir. All of these are natural fibers derived from plants.

2. **Analyzing Each Fiber**:
- **Jute**: Jute is known for its long, soft, and shiny fibers. It is classified as a bast fiber, which means it comes from the inner bark of the plant. Jute fibers are quite long and are often used in making burlap and other textiles.
- **Cotton**: Cotton fibers are relatively shorter compared to jute. They are soft and fluffy but do not reach the length of jute fibers.
- **Sun Hemp**: Sun hemp fibers are also shorter than jute. They are used in making ropes and other products but are not as long as jute fibers.
- **Coir**: Coir fibers come from the husk of coconuts. While they are strong and durable, they are also shorter than jute fibers.

3. **Comparing Fiber Lengths**:
- Among the four options, jute is recognized for having the longest fibers. The other fibers (cotton, sun hemp, and coir) are comparatively shorter.

4. **Conclusion**:
- Based on the analysis, the longest fibers are found in **(a) Jute**.

### Final Answer:
The correct answer is **(a) Jute**.
