C. Tuber, Bulb
D. Sucker, Rhizome

Answer

To solve the question regarding the commercial propagation of banana and ginger, we need to identify the specific parts of these plants that are utilized for propagation.

### Step-by-Step Solution:

1. **Understanding Banana Propagation**:
- Banana plants do not propagate from seeds. Instead, they are primarily propagated through a part called "sucker" or "corm."
- The sucker is a shoot that grows from the base of the banana plant and can be separated to grow a new plant.

2. **Understanding Ginger Propagation**:
- Ginger propagates through a part known as "rhizome."
- A rhizome is an underground stem that grows horizontally and has nodes from which new shoots can emerge.

3. **Analyzing the Options**:
- The options provided are:
1. Rhizome and corm
2. Rhizome and tuber
3. Tuber and bulb
4. Corm and rhizome
- We need to match the correct parts with the respective plants.

4. **Evaluating Each Option**:
- **Option 1**: Rhizome and corm - Incorrect, as banana uses corm (sucker), not rhizome.
- **Option 2**: Rhizome and tuber - Incorrect, as ginger uses rhizome, but banana does not use tuber.
- **Option 3**: Tuber and bulb - Incorrect, as tuber is for potato and bulb is for onion.
- **Option 4**: Corm and rhizome - Correct, as banana uses corm and ginger uses rhizome.

5. **Conclusion**:
- The correct answer is **Option 4: Corm for banana and rhizome for ginger**.
