Select the incorrect pair.

Options

A. `{:("Organism ","Mode of multiplication"),("Agave,Oxalis","Bulbils "):}`
B. `{:("Organism ","Mode of multiplication"),("Amoeba, paramecium","Binary fission "):}`
C. `{:("Organism ","Mode of multiplication"),("Chlamydomonas","Sporangiospores"):}`
D. `{:("Organism ","Mode of multiplication"),("Ginger, Banana","Rhizome"):}`

Answer

To solve the question of selecting the incorrect pair, we will analyze each option provided and determine whether the organism and its mode of reproduction or multiplication are correctly matched.

### Step-by-Step Solution:

1. **First Option: Agave or Oxalis - Bulbils**
- **Analysis**: Both Agave and Oxalis can reproduce through bulbils, which are small bulbs that form in the leaf axils. This is a correct pairing.
- **Conclusion**: This option is correctly matched.

2. **Second Option: Amoeba and Paramecium - Binary Fission**
- **Analysis**: Both Amoeba and Paramecium reproduce asexually through binary fission, where the organism divides into two equal parts. This is also a correct pairing.
- **Conclusion**: This option is correctly matched.

3. **Third Option: Chlamydomonas - Sporangiospores**
- **Analysis**: Chlamydomonas primarily reproduces asexually through zoospores, not sporangiospores. Sporangiospores are produced in fungi and not in Chlamydomonas.
- **Conclusion**: This option is incorrectly matched.

4. **Fourth Option: Ginger - Rhizome**
- **Analysis**: Ginger reproduces asexually through rhizomes, which are modified stems that grow horizontally underground. This is a correct pairing.
- **Conclusion**: This option is correctly matched.

### Final Answer:
The incorrect pair is the **third option**: Chlamydomonas - Sporangiospores.
