A non-renewable resource is

Options

A. forest
B. coal
C. water
D. wildlife.

Explanation

### Step-by-Step Solution:

1. **Understanding Non-Renewable Resources**:
- Non-renewable resources are natural resources that cannot be replenished or replaced at the same rate they are consumed. Once they are used up, they are gone for a long time, if not permanently.

2. **Characteristics of Non-Renewable Resources**:
- They exist in finite amounts.
- They cannot be replenished quickly or at all once they are consumed.
- Examples include fossil fuels (like coal, oil, and natural gas) and minerals.

3. **Examples of Non-Renewable Resources**:
- Fossil Fuels: Coal, oil, and natural gas are primary examples of non-renewable resources.
- Nuclear Energy: This is derived from uranium, which is also finite.
- Minerals: Metals like gold, silver, and copper are non-renewable as they are mined from the earth.

4. **Distinguishing from Renewable Resources**:
- Renewable resources are those that can be replenished naturally over time, such as sunlight, wind, and water. They can be used continuously without the risk of depletion.

5. **Conclusion**:
- Based on the definitions and examples provided, the correct answer to the question "A non-renewable resource is" would be coal, as it is a fossil fuel that cannot be replaced once it is consumed.
