### Step-by-Step Solution

1. **Understanding the Earthworm's Anatomy**:
- The earthworm's body is segmented, which means it is divided into multiple sections or segments. Each segment has specific functions and characteristics.

2. **Identifying the Clitellum**:
- The clitellum is a specific structure in earthworms that is responsible for reproduction. It is not found in all segments but is located in a specific region.

3. **Locating the Segments**:
- The clitellum is present in the 14th, 15th, and 16th segments of the earthworm. These segments are unique because they are fused together and do not exhibit the typical segmentation found in other parts of the earthworm's body.

4. **Function of the Clitellum**:
- The clitellum is glandular in nature, meaning it contains glands that secrete a viscous fluid. This fluid plays a crucial role in the reproductive process, particularly in the storage of eggs.

5. **Conclusion**:
- Therefore, the correct answer to the question regarding the segments in which the clitellum is present in an earthworm is the 14th, 15th, and 16th segments.
