D. Ginger

Answer

To solve the question "Stem takes part in storage and perennation in," we need to analyze the options provided: wheat, groundnut, radish, and ginger.

### Step-by-Step Solution:

1. **Understanding the Question**: The question is asking which plant has a stem that is modified for storage and perennation (survival during unfavorable conditions).

2. **Analyzing the Options**:
- **Wheat**: Wheat is primarily a cereal grain and its storage organs are the seeds, not the stem.
- **Groundnut**: Groundnut (peanut) is a legume and its storage organ is the pod, not the stem.
- **Radish**: Radish is a root vegetable where the edible part is the root, not a modified stem.
- **Ginger**: Ginger is known to be a rhizome, which is a modified stem that grows underground.

3. **Identifying the Characteristics of Ginger**:
- Ginger acts as a storage organ for food (starch) which helps the plant survive during drought conditions.
- It has nodes and internodes, which are typical features of stems.

4. **Conclusion**: Based on the analysis, ginger is the only option where the stem (as a rhizome) is involved in storage and perennation.

Thus, the correct answer is **ginger**.
