Complete the analogy
Amoeba: Simple binary fission::paramecium: Choose the correct option.

Options

A. Longitudinal binary fission
B. Simple binary fission
C. Oblique binary fission
D. Transverse binary fission

Answer

To complete the analogy "Amoeba: Simple binary fission:: Paramecium: ?", we need to identify the type of binary fission that Paramecium undergoes, similar to how Amoeba undergoes simple binary fission.

### Step-by-Step Solution:

1. **Understand the Concept of Binary Fission**: Binary fission is a method of asexual reproduction where a single organism divides into two parts, each developing into a new organism.

2. **Identify the Type of Binary Fission in Amoeba**: Amoeba reproduces through a process called simple binary fission. In this process, the organism divides into two equal halves.

3. **Explore the Types of Binary Fission**: There are four types of binary fission:
- **Irregular Binary Fission**: Division can occur through any plane (example: Amoeba).
- **Longitudinal Binary Fission**: Division occurs along the longitudinal axis (example: Euglena).
- **Transverse Binary Fission**: Division occurs along the transverse axis (example: Paramecium).
- **Oblique Binary Fission**: Division occurs at an oblique angle (example: Serratia).

4. **Determine the Type of Binary Fission in Paramecium**: Paramecium undergoes transverse binary fission, where the organism divides along its transverse axis.

5. **Complete the Analogy**: Since Amoeba is to simple binary fission as Paramecium is to transverse binary fission, the correct completion of the analogy is:
- **Amoeba: Simple binary fission:: Paramecium: Transverse binary fission**.

6. **Select the Correct Option**: Among the options provided, the one that corresponds to the type of binary fission in Paramecium is "transverse binary fission".

### Final Answer:
The correct option is **transverse binary fission**.
