Increasing skin cancer and high mutation rate are the result of

Options

A. ozone depletion
B. acid rain
C. CO pollution
D. `CO_(2)` pollution.

Explanation

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the causes of increasing skin cancer and a high mutation rate. We need to identify which of the given options (ozone depletion, acid rain, CO pollution, or CO2 pollution) is responsible for these issues.

2. **Analyzing the Options**:
- **Option A: Ozone Depletion**: Ozone depletion occurs in the stratosphere due to the release of chlorofluorocarbons (CFCs). The ozone layer protects the Earth from harmful ultraviolet (UV) radiation from the sun. When this layer is depleted, more UV radiation reaches the Earth's surface, which can lead to an increase in skin cancer and mutations in DNA.
- **Option B: Acid Rain**: Acid rain is primarily caused by the emission of sulfur dioxide and nitrogen oxides, which can harm ecosystems but is not directly linked to skin cancer or mutation rates.
- **Option C: CO Pollution**: Carbon monoxide (CO) pollution is primarily a concern for respiratory health and does not have a direct link to skin cancer or mutation rates.
- **Option D: CO2 Pollution**: Carbon dioxide (CO2) is a greenhouse gas that contributes to climate change but does not directly cause skin cancer or mutations.

3. **Conclusion**: Based on the analysis, the correct answer is **ozone depletion (Option A)**. The depletion of the ozone layer leads to increased UV radiation, which is responsible for higher rates of skin cancer and mutations.

### Final Answer:
Increasing skin cancer and high mutation rate are the result of **ozone depletion**.
