Identify the wrong statement in the following:

Options

A. Acid rain is mostly because of oxides of nitrogen and sulphur
B. Chlorofluorocarbons are responsible for ozone layer depletion
C. Greenhouse effect is responsible for global warming
D. Ozone layer does not permit infrared radiation from the sun to reach the earth.

Answer

To identify the wrong statement from the provided options regarding environmental pollution, we can analyze each statement step by step.

### Step-by-Step Solution:

1. **Understanding Acid Rain**:
- Acid rain is primarily caused by the presence of oxides of nitrogen (NOx) and sulfur (SOx) in the atmosphere.
- When these oxides react with water vapor in the atmosphere, they form acids (like sulfuric acid and nitric acid), which fall as acid rain.

2. **Evaluating the First Statement**:
- The first statement claims that acid rain is mostly due to oxides of nitrogen and sulfur. This statement is **correct**.

3. **Evaluating the Second Statement**:
- The second statement mentions that chlorofluorocarbons (CFCs) are responsible for ozone layer depletion. This is also **correct** as CFCs break down ozone in the stratosphere when exposed to UV radiation.

4. **Evaluating the Third Statement**:
- The third statement states that the greenhouse effect is responsible for global warming. This statement is **correct**. Greenhouse gases trap heat in the atmosphere, leading to an increase in global temperatures.

5. **Evaluating the Fourth Statement**:
- The fourth statement claims that the ozone layer does not permit infrared radiation from the sun to reach the Earth. This statement is **incorrect**.
- The ozone layer primarily protects against harmful ultraviolet (UV) radiation, while infrared radiation is not blocked by the ozone layer and is essential for warming the Earth's surface.

### Conclusion:
- The incorrect statement is the **fourth statement**: "Ozone layer does not permit infrared radiation from the sun to reach the earth."
