Answer

To answer the question "A pitcher with nest root occurs in", we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking about a specific plant that has a pitcher structure and nest roots.

2. **Identify Key Terms**:
- **Pitcher**: A modified leaf structure in some plants that forms a pitcher-like shape, often used for trapping insects.
- **Nest Roots**: These are adventitious roots that develop from parts of the plant other than the radical (the primary root).

3. **Consider the Options**: The plants mentioned in the context are likely to be insectivorous plants, which include:
- **Dystidia**
- **Nepenthes**
- **Sarracenia**

4. **Analyze Each Plant**:
- **Dystidia**: The leaves are modified into open pitchers. The nest roots in this plant absorb rainwater collected in the pitcher.
- **Nepenthes**: This plant has pitchers that are designed to trap and digest insects, and they have a lid structure.
- **Sarracenia**: Similar to Nepenthes, it has pitchers for trapping insects and also features a lid.

5. **Determine the Correct Answer**: Based on the analysis, Dystidia is the plant that has a pitcher structure with nest roots that absorb rainwater, while Nepenthes and Sarracenia are primarily focused on insect trapping.

6. **Final Answer**: The correct answer is **Dystidia**.
