Chose the correct pair(s).
I. Irregular binary fission - Amoeba
II. Longitudinal binary fissionn - Euglena
III. Transverse binary fission - Paramecium
IV. Multiple fission - Plasmodium
Select the correct codes.

Options

A. I, III and IV
B. I, II and III
C. II and IV
D. All of these

Answer

To solve the question, we need to evaluate each of the given pairs to determine if they are correctly matched. Let's analyze each pair step by step.

### Step 1: Analyze the first pair
**I. Irregular binary fission - Amoeba**
- Amoeba reproduces by a process known as binary fission, which is irregular due to its amorphous shape. The division can occur in various orientations.
- **Conclusion**: This pair is correct.

### Step 2: Analyze the second pair
**II. Longitudinal binary fission - Euglena**
- Euglena undergoes binary fission in a longitudinal manner, meaning it divides along its length.
- **Conclusion**: This pair is correct.

### Step 3: Analyze the third pair
**III. Transverse binary fission - Paramecium**
- Paramecium reproduces by transverse binary fission, where it divides horizontally across its body.
- **Conclusion**: This pair is correct.

### Step 4: Analyze the fourth pair
**IV. Multiple fission - Plasmodium**
- Plasmodium reproduces through multiple fission, where one cell divides into many daughter cells simultaneously.
- **Conclusion**: This pair is correct.

### Final Conclusion
All four pairs are correctly matched:
- I. Correct
- II. Correct
- III. Correct
- IV. Correct

Thus, the correct answer is that all pairs are correct.
