Which one of the following pairs is mismatched ?

Options

A. Fossil fuel burning - release of `CO_2`
B. Nuclear power - radioactive wastes
C. Solar energy - green house effect
D. Biomass burning - relase of `CO_2`

Answer

To determine which pair is mismatched, we will analyze each option provided in the question:

1. **Fossil Fuel Burning - Release of Carbon Dioxide**
- When fossil fuels (like coal, oil, and natural gas) are burned, they release carbon dioxide (CO2) into the atmosphere. This is a well-known fact as fossil fuel combustion is a major source of greenhouse gases, contributing to global warming.
- **Conclusion**: This pair is correctly matched.

2. **Nuclear Power - Radioactive Waste**
- Nuclear power generation involves the use of nuclear reactions to produce energy. After the nuclear fuel (like uranium) has been used in a reactor, it becomes radioactive waste. This waste is hazardous and must be managed carefully.
- **Conclusion**: This pair is also correctly matched.

3. **Solar Energy - Greenhouse Effect**
- Solar energy is harnessed from sunlight and does not produce air pollution or greenhouse gases during its generation. The greenhouse effect is caused by greenhouse gases (like CO2, methane, etc.) trapping heat in the atmosphere, which is not a result of solar energy production.
- **Conclusion**: This pair is mismatched.

4. **Biomass Burning - Release of Carbon Dioxide**
- Biomass burning involves the combustion of organic materials (like wood, crops, and waste), which releases carbon dioxide as a byproduct. While it is considered renewable, it still contributes to CO2 emissions.
- **Conclusion**: This pair is correctly matched.

Based on the analysis above, the mismatched pair is:

**Answer**: Solar Energy - Greenhouse Effect
