In amoeba reproduction takes place by __________

Options

A. external fertilisation
B. internal fertilisation
C. budding
D. binary fission

Explanation

**Step-by-Step Solution:**

1. **Identify the Organism**: The question asks about the reproduction method in amoeba. Amoeba is a single-celled organism that belongs to the group of protozoa.

2. **Understand the Reproductive Method**: Amoeba reproduces asexually. Asexual reproduction means that the organism can reproduce without the involvement of gametes (sperm and egg).

3. **Determine the Specific Process**: The specific method of asexual reproduction in amoeba is called binary fission. This is a process where the parent organism divides into two identical daughter cells.

4. **Explain the Process of Binary Fission**:
- The amoeba first elongates, preparing for division.
- The nucleus of the amoeba divides into two.
- The cytoplasm (cell material) also divides.
- Finally, this results in the formation of two separate daughter amoebas, each a clone of the parent.

5. **Conclusion**: Therefore, the correct answer to the question is that in amoeba, reproduction takes place by **binary fission**.
