Air pollutants capse serious damage to health.
Which gas is paired correctly with the disease caused by it?
(A)Smoge-Asthama (B) CO- Lung damage (C) `SO_(2)`-Skin disease

Options

A. Smong-Asthama
B. CO-Lung damage
C. `SO_2` - Skin disease
D. Chlorofluorocarbons - Reduce the oxygen carrying capacity of blood.

Answer

To solve the question about which gas is correctly paired with the disease it causes, we will analyze each option provided.

### Step-by-Step Solution:

1. **Identify the gases and their associated diseases:**
- (A) Smog - Asthma
- (B) CO (Carbon Monoxide) - Lung damage
- (C) SO₂ (Sulfur Dioxide) - Skin disease

2. **Evaluate each option:**
- **Option (A): Smog - Asthma**
- Smog is a type of air pollution that can trigger asthma attacks and worsen respiratory conditions. This pairing is correct.

- **Option (B): CO - Lung damage**
- Carbon monoxide (CO) is a colorless, odorless gas that can cause serious health issues, primarily affecting the cardiovascular system and reducing the oxygen-carrying capacity of blood rather than directly causing lung damage. This pairing is not entirely accurate.

- **Option (C): SO₂ - Skin disease**
- Sulfur dioxide (SO₂) is known to cause respiratory issues and is a component of acid rain, but it is not typically associated with skin diseases. This pairing is incorrect.

3. **Conclusion:**
- The correct pairing is **(A) Smog - Asthma**.

### Final Answer:
The gas paired correctly with the disease caused by it is **(A) Smog - Asthma**.
