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- release of `CO_(2)`

Answer

To determine which pair is mismatched, we will analyze each of the given options step by step.

1. **Option 1: Fossil Fuel Burning and Release of Carbon Dioxide**
- Burning fossil fuels (like coal, oil, and natural gas) releases carbon dioxide (CO2) into the atmosphere. This is a well-established fact as fossil fuels are carbon-based and their combustion results in CO2 emissions.
- **Conclusion**: This pair is correctly matched.

2. **Option 2: Nuclear Power and Radioactive Waste**
- Nuclear power generation involves the fission of uranium or other radioactive materials, which produces energy. However, this process also generates radioactive waste that must be managed and stored safely.
- **Conclusion**: This pair is correctly matched.

3. **Option 3: Solar Energy and Greenhouse Effect**
- Solar energy is harnessed from the sun and does not produce emissions or pollutants. The greenhouse effect is caused by the retention of heat in the atmosphere due to greenhouse gases, which can include CO2, methane, and others. Solar energy itself does not contribute to the greenhouse effect; rather, it is the accumulation of greenhouse gases that leads to this phenomenon.
- **Conclusion**: This pair is mismatched.

4. **Option 4: Biomass Burning and Release of Carbon Dioxide**
- Burning biomass (like wood, crop waste, etc.) also releases carbon dioxide into the atmosphere. Similar to fossil fuels, biomass combustion is a source of CO2 emissions.
- **Conclusion**: This pair is correctly matched.

**Final Answer**: The mismatched pair is **Solar Energy and Greenhouse Effect** (Option 3).
