Select the mismatched pair out of the following

Options

A. a) Rhizome -Druopteris,Nelumbo nucifera
B. b) Corm -Crocus sativus, Amorphophallus
C. c) Sucker-Curcuma domestica, Zingiber offcinale
D. d) Tuber-Helianthus tuberosus,Solanum tuberosum

Explanation

To solve the question of selecting the mismatched pair from the given options, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Rhizome**: An underground stem that grows horizontally. Examples include *Triopteris* and *Nilumbo nucifera*.
- **Corm**: An underground stem that is short and vertical. Examples include *Crocus sativus* and *Amorphophallus*.
- **Sucker**: A stem that arises from the underground and grows horizontally, promoting asexual reproduction.
- **Tuber**: A modified underground stem that stores food. Examples include *Helianthus tuberosus* and *Solanum tuberosum*.

2. **Analyzing Each Option**:
- **Option A**: Rhizome - *Triopteris* and *Nilumbo nucifera* are correct examples. This pair is matched correctly.
- **Option B**: Corm - *Crocus sativus* and *Amorphophallus* are correct examples. This pair is matched correctly.
- **Option C**: Sucker - The examples given are *Curcuma domestica* and *Zingiber officinale*. However, both of these are actually rhizomes, not suckers. Therefore, this pair is mismatched.
- **Option D**: Tuber - *Helianthus tuberosus* and *Solanum tuberosum* are correct examples. This pair is matched correctly.

3. **Conclusion**:
- After analyzing all options, we find that **Option C** is the mismatched pair because the examples given do not correctly represent suckers; they are rhizomes instead.

### Final Answer:
The mismatched pair is **Option C**: Suckers - *Curcuma domestica* and *Zingiber officinale*.
