The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Methanogens**: Methanogens are a type of anaerobic microbes, meaning they thrive in environments devoid of oxygen. This characteristic is crucial for their metabolic processes. 2. **Process of Methanogenesis**: Methanogens are known for a specific metabolic process called methanogenesis. This process involves the conversion of substrates (like carbon dioxide and hydrogen) into methane gas (CH4). 3. **Byproducts of Methanogenesis**: During methanogenesis, methanogens also produce other gases as byproducts. These include hydrogen sulfide (H2S) and carbon dioxide (CO2). 4. **Analyzing the Options**: - **Option A (Oxygen)**: Methanogens do not produce oxygen. In fact, they function in the absence of oxygen, making this option correct. - **Option B (Methane)**: Methane is the primary product of methanogenesis, so this option is incorrect. - **Option C (Hydrogen sulfide)**: Hydrogen sulfide is one of the byproducts produced by methanogens, making this option incorrect. - **Option D (Carbon dioxide)**: Carbon dioxide is also produced during the process of methanogenesis, so this option is incorrect. 5. **Conclusion**: Based on the analysis of the options, the correct answer is (a) Oxygen, as methanogens do not produce oxygen. **Final Answer**: (a) Oxygen ---
