Which one following is correctly matched.

Options

A. Onion - Bulb
B. Ginger - Sucker
C. Chlamydomonas - Sucker
D. Yeast - Zoospores

Explanation

To solve the question of which option is correctly matched regarding vegetative propagation, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Vegetative Propagation**:
- Vegetative propagation is a form of asexual reproduction in plants where new individuals are produced from vegetative parts like stems, roots, or leaves.

2. **Analyzing the Options**:
- We have four options to evaluate:
1. Onion - Bulbs
2. Ginger - Suckers
3. Chlamydomonas - Suckers
4. Yeast - Zoospores

3. **Evaluating Option 1: Onion - Bulbs**:
- Onions propagate through bulbs, which are underground stems that contain condensed shoots and buds. This is a correct match.
- **Conclusion**: This option is correctly matched.

4. **Evaluating Option 2: Ginger - Suckers**:
- Ginger propagates through rhizomes, not suckers. Suckers are slender underground branches that develop from the base of aerial shoots, which is not applicable to ginger.
- **Conclusion**: This option is incorrectly matched.

5. **Evaluating Option 3: Chlamydomonas - Suckers**:
- Chlamydomonas is a unicellular green algae that reproduces via zoospores, not suckers. Suckers are not relevant to Chlamydomonas.
- **Conclusion**: This option is incorrectly matched.

6. **Evaluating Option 4: Yeast - Zoospores**:
- Yeast reproduces by budding, not through zoospores. Zoospores are associated with certain algae and fungi, but not with yeast.
- **Conclusion**: This option is incorrectly matched.

7. **Final Conclusion**:
- The only correctly matched pair is **Option 1: Onion - Bulbs**.

### Summary of the Solution:
The correctly matched option is **Option 1: Onion - Bulbs**.
