Answer

To determine the segments of the earthworm where the genital papillae are present, follow these steps:

### Step-by-Step Solution:

1. **Understand the Anatomy of the Earthworm**:
- The earthworm has a segmented body. Each segment has specific structures and functions.

2. **Identify the Key Segments**:
- The anterior end of the earthworm starts with the prostomium (first segment) followed by the peristomium (second segment).
- After these, the segments are numbered starting from 3 onward.

4. **Examine Segments 17, 18, and 19**:
- After the clitellum, segments 17, 18, and 19 are important for reproductive structures.
- Segment 17 contains two openings known as genital papillae.
- Segment 19 also contains two openings referred to as genital papillae.

5. **Identify the Correct Answer**:
- The question asks for the segments where genital papillae are present. Based on the anatomy, genital papillae are located in segments 17 and 19.

### Final Answer:
