Which of the following pairs is mismatched ?

Options

A. Biomass burning-Release of sulphur dioxide
B. Fossil fuel burning- Release of carbon dioxide
C. Nuclear power- Radioactive wastes
D. Water vapour- Green house effect

Answer

To solve the question "Which of the following pairs is mismatched?", we need to analyze each option provided and determine if the pair correctly represents the relationship between the two elements.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- A) Biomass burning - release of sulphur dioxide
- B) Fossil fuel burning - release of carbon dioxide
- C) Nuclear power - radioactive waste
- D) Water vapour - greenhouse effect

2. **Analyze Each Option**:
- **Option A (Biomass burning - release of sulphur dioxide)**: Biomass burning primarily produces carbon dioxide (CO2) as a result of combustion. While it may also release some sulphur dioxide (SO2), the main gas produced is CO2. Therefore, this pair is mismatched.

- **Option B (Fossil fuel burning - release of carbon dioxide)**: This is a correct match. Burning fossil fuels like coal and petroleum predominantly releases carbon dioxide.

- **Option C (Nuclear power - radioactive waste)**: This is also a correct match. Nuclear power generation produces radioactive waste as a byproduct.

- **Option D (Water vapour - greenhouse effect)**: This is a correct match as well. Water vapour is a significant greenhouse gas that contributes to the greenhouse effect by trapping heat in the atmosphere.

3. **Conclusion**: After analyzing all options, we find that the mismatched pair is **Option A**: Biomass burning - release of sulphur dioxide.

### Final Answer:
The mismatched pair is **Option A: Biomass burning - release of sulphur dioxide**.
