Options

A. Rain
B. Mining
C. Construction
D. Deforestation

Answer

To determine which of the activities represents a natural phenomenon, we can analyze each option provided.

### Step-by-Step Solution:

1. **Identify the Activities**: We have four activities to consider: deforestation, construction, mining, and rain.

2. **Define Deforestation**: Deforestation refers to the clearing or thinning of forests by humans. It is primarily driven by the need for land for agriculture, urban development, and other human activities. Since it is caused by human actions, it is not a natural phenomenon.

3. **Define Construction**: Construction involves building structures such as houses, roads, and bridges. This activity is also driven by human needs and is therefore considered manmade, not a natural phenomenon.

4. **Define Mining**: Mining is the process of extracting minerals and ores from the earth. Similar to deforestation and construction, mining is a human activity aimed at obtaining resources, making it manmade and not a natural phenomenon.

5. **Define Rain**: Rain is a natural occurrence that happens when water vapor in the atmosphere condenses and falls to the ground. It is a part of the water cycle and occurs without human intervention, making it a natural phenomenon.

6. **Conclusion**: Among the activities listed, rain is the only one that represents a natural phenomenon.

### Final Answer:
The activity that represents a natural phenomenon is **rain**.
