Which form of reproduction is correctly matched ?

Options

A. Euglena `rarr` transverse binary fission
B. Paramecium `rarr` longitudinal binary fission
C. Amoeba `rarr` multiple fission
D. Plasmodium `rarr` binary fission

Explanation

To solve the question "Which form of reproduction is correctly matched?", we will analyze the options provided and determine which one accurately describes the form of reproduction associated with each organism.

### Step-by-Step Solution:

1. **Understanding Binary Fission**:
- Binary fission is a type of asexual reproduction commonly seen in unicellular organisms. In this process, a single organism divides into two identical daughter cells.
- It involves karyokinesis (division of the nucleus) followed by cytokinesis (division of the cytoplasm).

2. **Analyzing the Options**:
- **Option 1: Euglena shows binary fission**.
- Euglena typically undergoes longitudinal binary fission, where the organism divides along its length. However, this option is not correctly matched as it is not the only method of reproduction for Euglena.

- **Option 2: Paramecium shows longitudinal binary fission**.
- Paramecium actually undergoes transverse binary fission, where the division occurs across its width. Therefore, this option is incorrectly matched.

- **Option 3: Amoeba shows multiple fission**.
- Amoeba can undergo multiple fission, especially during unfavorable conditions. In this process, the amoeba forms a protective cyst and divides into several daughter cells. This option is correctly matched.

- **Option 4: Plasmodium shows binary fission**.
- Plasmodium primarily reproduces through multiple fission (schizogony), not binary fission. Therefore, this option is also incorrectly matched.

3. **Conclusion**:
- The only correctly matched option is **Option 3: Amoeba shows multiple fission**.

### Final Answer:
The correct answer is **Option 3: Amoeba shows multiple fission**.
