The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Bacterial Reproduction**: Bacteria are unicellular organisms that reproduce primarily through a process called binary fission. This is a form of asexual reproduction where a single bacterial cell divides into two identical daughter cells. 2. **Identifying the Main Method**: The question specifically asks how bacteria multiply mainly. The term "mainly" indicates that we should focus on the most common method of reproduction in bacteria. 3. **Binary Fission Process**: In binary fission, the bacterial cell undergoes several steps: - The bacterial DNA is replicated. - The cell elongates. - The cell membrane pinches inward, dividing the cell into two parts. - Two genetically identical daughter cells are formed. 4. **Types of Binary Fission**: While binary fission is the main method of reproduction, it can occur in different forms: - **Transverse Binary Fission**: The cell divides across its width. - **Longitudinal Binary Fission**: The cell divides along its length. - **Oblique Binary Fission**: The cell divides at an angle. 5. **Correct Answer**: Among these types, transverse binary fission is the most common method observed in bacteria. Therefore, the correct answer to the question is that bacteria mainly multiply by transverse binary fission. **Final Answer**: Bacteria mainly multiply by transverse binary fission. ---
