Which of the following is not correctly matched ?

Options

A. Water pollution - using synthetic detergents for washing clothes
B. Photochemical smog - releasing gases produced by automobiles and factories
C. Darmaging ozone layer- using CFCS
D. Acid rain - releasing pesticides and fertilizers in water

Explanation

To determine which of the following options is not correctly matched, we will analyze each option one by one.

### Step 1: Analyze Option 1
**Option 1:** Water pollution is caused due to using synthetic detergents for washing clothes.
- **Analysis:** This statement is correct. Synthetic detergents contain phosphates that can lead to water pollution when they enter water bodies, disrupting the ecological balance and harming aquatic life.

### Step 2: Analyze Option 2
**Option 2:** Photochemical smog is due to the release of gases produced by automobiles and factories.
- **Analysis:** This statement is also correct. Photochemical smog forms when sunlight reacts with pollutants like nitrogen oxides and volatile organic compounds emitted by vehicles and industrial processes.

### Step 3: Analyze Option 3
**Option 3:** Damaging ozone layer is caused by CFCs.
- **Analysis:** This statement is correct as well. Chlorofluorocarbons (CFCs) released from various sources, including refrigerators and air conditioners, deplete the ozone layer, which protects the Earth from harmful UV radiation.

### Step 4: Analyze Option 4
**Option 4:** Acid rain is caused due to the release of pesticides and fertilizers in water.
- **Analysis:** This statement is incorrect. Acid rain is primarily caused by the release of sulfur oxides and nitrogen oxides into the atmosphere, which react with water vapor to form sulfuric acid (H₂SO₄) and nitric acid (HNO₃). Pesticides and fertilizers do not directly cause acid rain.

### Conclusion
Based on the analysis, the option that is not correctly matched is **Option 4**: Acid rain is caused due to the release of pesticides and fertilizers in water.
