The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Biogas**: Begin by recognizing what biogas is. Biogas is a renewable energy source produced from the decomposition of organic matter, primarily used for cooking and heating. 2. **Identifying Substitutes**: The question asks for a good substitute for biogas. The common substitutes for cooking energy include fuel wood, petroleum, oil, coal, and charcoal. 3. **Evaluating Options**: - **Charcoal**: While charcoal can be used for cooking, it is not a direct substitute for biogas in the same way fuel wood is. Therefore, it can be ruled out. - **Coal**: Coal is not commonly used for cooking due to its lower efficiency and higher pollution levels compared to biogas. Thus, it is also not a suitable substitute. - **Petroleum and Oil**: These are typically used for transportation and heating, but they are not practical substitutes for biogas in cooking. - **Fuel Wood**: Historically, fuel wood has been the primary source for cooking before the advent of biogas. It is readily available in many developing countries and serves as a direct substitute for biogas. 4. **Conclusion**: After evaluating all options, it is clear that the best substitute for biogas is fuel wood. Additionally, in developing countries, the heaviest demand on forests is primarily for fuel wood, as it is extensively used for cooking and heating. 5. **Final Answer**: Biogas can be a good substitute for **fuel wood**. In developing countries, the heaviest demand on forests is for **fuel wood**. ---
