Mist is fog with horizontal visibility of

Options

A. 100 m
B. 200 m
C. 500 m
D. 1km

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the definition of mist in terms of horizontal visibility. We need to identify the specific visibility range that characterizes mist.

2. **Defining Mist and Fog**: Mist is often confused with fog. Both are forms of atmospheric moisture, but they differ in visibility. Fog typically has a visibility of less than 1 kilometer, while mist has a higher visibility.

3. **Analyzing Visibility Ranges**:
- Fog generally has a visibility of less than 1 kilometer.
- Mist, on the other hand, is characterized by a visibility that is greater than 1 kilometer but can be less than 2 kilometers.

4. **Evaluating the Options**: The options given are:
- 100 meters
- 200 meters
- 500 meters
- 1 kilometer

Since mist has visibility greater than 1 kilometer, we can eliminate the first three options (100 meters, 200 meters, and 500 meters).

5. **Conclusion**: The correct answer is that mist is fog with a horizontal visibility of **1 kilometer or more**.

**Final Answer**: Mist is fog with horizontal visibility of **1 kilometer or more**.
