Let's carefully analyze the characteristics of each of the atmospheric layers of the Sun described in the table and match these characteristics with the known data about the Sun's layers.
We have the following data for each layer:
Column A:
- Position: Lowest
- Thickness: 100 km
- Temperature: 5,500 K
Column B:
- Position: Middle
- Thickness: 2000 km
- Temperature: 6,000 to 20,000 K
Column C:
- Position: Outermost
- Thickness: Millions of kilometers
- Temperature: 2,000,000 K
Now let's match these characteristics with the known layers of the Sun:
1. Photosphere:
- Position: Lowest atmospheric layer of the Sun
- Thickness: About 100 km
- Temperature: Approximately 5,500 K
Based on this, Column A matches the Photosphere.
2. Chromosphere:
- Position: Middle atmospheric layer of the Sun
- Thickness: About 2000 km
- Temperature: Ranges from about 6,000 K to 20,000 K
Hence, Column B matches the Chromosphere.
3. Corona:
- Position: Outermost atmospheric layer of the Sun
- Thickness: Extends for millions of kilometers into space
- Temperature: Around 2,000,000 K
This means Column C matches the Corona.
Therefore, the correct sequence from the given options can be identified as:
- A: Photosphere
- B: Chromosphere
- C: Corona
Thus, the correct answer is:
A: Photosphere; B: Chromosphere; C: Corona
