Ginger is multiplied vegetatively by means of

Options

A. Bud
B. Tuber
C. Corm
D. rhizomes

Answer

### Step-by-Step Solution:

1. **Understanding Vegetative Reproduction**: Vegetative reproduction is a form of asexual reproduction in plants where new individuals are formed without the production of seeds or spores. This process can occur through various structures.

2. **Identifying the Options**: The options given are:
- Birds
- Tuber
- Corm
- Rhizomes

3. **Analyzing Each Option**:
- **Birds**: These are fleshy, non-green, underground stems that help in vegetative reproduction in some plants, like sweet potato, but are not related to ginger.
- **Tuber**: Tubers, such as those found in potatoes, are swollen underground stems that store nutrients and can produce new plants. However, they are not the method of vegetative reproduction for ginger.
- **Corm**: Corms are swollen underground stems that serve as storage organs and can give rise to new plants, as seen in plants like gladiolus. However, ginger does not reproduce via corms.
- **Rhizomes**: Rhizomes are horizontal underground stems that can produce new shoots and roots. They are a common method of vegetative reproduction in many plants, including ginger.

4. **Conclusion**: Based on the analysis, ginger is multiplied vegetatively by means of rhizomes.

5. **Final Answer**: The correct option is **rhizomes**.
