Which one of the following is correctly matched

Options

A. Banana - Corm
B. Colocasia - Offset.
C. Onion - Bulb
D. Ginger - Sucker

Answer

To determine which of the given options is correctly matched, we need to analyze each option based on the definitions of the terms involved.

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Comb**: This term typically refers to a type of underground stem that stores food. It is characterized by being fleshy and having scaly leaves or buds. However, the term "comb" is not commonly used in botanical terminology.
- **Offset**: An offset is a small, complete daughter plant that is produced asexually from the mother plant. It is a form of vegetative propagation and is seen in plants like lilies and tulips.
- **Bulb**: A bulb is a specialized underground bud, particularly of monocots. It consists of a short, fleshy storage structure with thick scales and is characterized by a vertical stem axis. An example of a bulb is the onion.
- **Sucker**: A sucker is a shoot that arises from the base of a plant or from its roots, which can develop into a new plant. Ginger is not classified as a sucker.

2. **Analyze Each Option**:
- **Banana - Comb**: This is incorrect. Bananas are known to have rhizomes, not combs.
- **Collocasia - Offset**: This is also incorrect. Collocasia (like taro) does not produce offsets in the same way as lilies or tulips.
- **Onion - Bulb**: This is correct. Onions are indeed classified as bulbs.
- **Ginger - Sucker**: This is incorrect. Ginger is a rhizome, not a sucker.

3. **Conclusion**:
The only correctly matched pair from the options provided is **Onion - Bulb**.

### Final Answer:
The correctly matched option is **Onion - Bulb**.
