Which of the following gases are response for acid rain ?

Options

A. `O_(2)(g)`
B. `CO(g)`
C. `CO_(2)(g)`
D. `SO_(2)(g),N`

Explanation

**Step-by-Step Solution:**

1. **Understanding Acid Rain**: Acid rain is a type of precipitation that is significantly more acidic than normal rainwater. It is primarily caused by the presence of certain gases in the atmosphere.

2. **Identifying the Gases**: The common gases that contribute to acid rain are sulfur dioxide (SO2) and nitrogen oxides (NOx, which includes nitrogen dioxide, NO2).

3. **Role of Sulfur Dioxide (SO2)**: When sulfur dioxide is released into the atmosphere, it can react with water vapor to form sulfuric acid (H2SO4). This reaction is a significant contributor to acid rain.

4. **Role of Nitrogen Oxides (NOx)**: Similarly, nitrogen oxides, particularly nitrogen dioxide (NO2), can react with water vapor to form nitric acid (HNO3). This also contributes to the acidity of rainwater.

5. **Conclusion**: Based on the reactions of these gases with water vapor, we conclude that both sulfur dioxide (SO2) and nitrogen oxides (NOx) are responsible for acid rain.

**Final Answer**: The gases responsible for acid rain are Sulfur Dioxide (SO2) and Nitrogen Oxides (NOx).
