D. Rhizome

Answer

To answer the question "Stem is most reduced in," we need to analyze the options provided and understand the concept of stem modifications in plants.

### Step-by-Step Solution:

1. **Understanding the Stem**: The stem is a crucial part of the plant that supports leaves and flowers and contains a continuous vascular system for transporting water, minerals, and nutrients.

2. **Identifying Stem Modifications**: In botany, stems can undergo modifications to adapt to different environmental conditions. Common modified stems include:
- Bulbs
- Corms
- Tubers
- Crowns
- Stolons
- Rhizomes

3. **Defining Bulbs**: Bulbs, such as those found in Allium cepa (onion) and Allium sativum (garlic), are characterized by a very short stem that is surrounded by fleshy leaves. This structure is designed for storage and survival during unfavorable conditions.

4. **Comparing Other Modifications**:
- **Corms** are swollen underground stems that store nutrients but are generally more developed than bulbs.
- **Tubers** (like potatoes) are also modified stems but are not as reduced as bulbs.
- **Rhizomes** are horizontal underground stems that can grow into new plants but are not reduced in the same way as bulbs.

5. **Conclusion**: Among the modified stem types, the bulb represents the most reduced form of the stem. Therefore, the correct answer to the question is that the stem is most reduced in bulbs.

### Final Answer:
The stem is most reduced in **bulbs** (e.g., Allium cepa and Allium sativum).
