**Explanation:**

**Climate** refers to the average weather conditions that prevail in a particular region over a long period of time, typically 30 years or more. It is not the same as weather, which refers to the short-term atmospheric conditions observed at a specific time and place.

**Climate is a statistical data of weather condition:**

- Climate is a statistical representation of the average weather conditions observed in a particular region over a long period of time. It takes into account various parameters such as temperature, precipitation, humidity, wind patterns, and atmospheric pressure.

- Climate data is collected over many years and is used to determine the typical weather patterns and trends in a specific area. This data is essential for understanding the climate of a region and predicting future weather conditions.

- Climate data is collected using various instruments and techniques such as weather stations, satellites, and climate models. These data sources provide information on temperature, rainfall, wind speed, and other atmospheric variables.

- By analyzing climate data, scientists can identify long-term trends and patterns in weather conditions. This information is crucial for understanding how climate change is impacting different regions and for making predictions about future climate scenarios.

**Climate is a data related to the atmosphere:**

- Climate is closely related to the Earth's atmosphere. The atmosphere is the layer of gases that surrounds the planet and plays a vital role in regulating its temperature and weather patterns.

- The composition and properties of the atmosphere have a direct impact on the climate of a region. For example, the concentration of greenhouse gases, such as carbon dioxide, in the atmosphere can influence the Earth's temperature and lead to changes in climate.

- Climate data includes information about atmospheric conditions such as temperature, humidity, air pressure, and wind patterns. These variables are important for understanding the climate of a region and how it may change over time.

**Conclusion:**

In conclusion, climate refers to the long-term average weather conditions observed in a particular region. It is a statistical representation of weather data collected over many years. Climate data is related to the atmosphere and includes information about various atmospheric variables. Therefore, the correct answer is option 'A' - Climate is a statistical data of weather condition.
