Taden has found a table of the atmospheric layers of the Sun. However, he can't make out the names of the layers in the chart.

| Position | Lowest | Middle | Outermost |
|-----------|----------|----------------|---------------------|
| Thickness | 100 km | 2000 km | Millions of km |
| Temperature | 5,500°C | 6,000 to 20,000°C | 2,000,000°C |

What are the names of the Sun's layers described in columns A, B, and C?

A. Corona; B. Photosphere; C. Chromosphere
B. Core; B. Chromosphere; C. Photosphere
C. Chromosphere; B. Corona; C. Core
D. Photosphere; B. Chromosphere; C. Corona

To determine the names of the Sun's layers described in columns A, B, and C, we will compare the details provided in each column with the known properties of the Sun's layers.

### Column A:
- Position: Lowest
- Thickness: 100 km
- Temperature: 5,500 K

This combination of attributes matches the Photosphere. The Photosphere is the lowest layer of the Sun's atmosphere, is about 100 km thick, and has an average temperature of approximately 5,500 K.

### Column B:
- Position: Middle
- Thickness: 2000 km
- Temperature: 6,000 to 20,000 K

These attributes correspond to the Chromosphere. The Chromosphere is a middle layer, with a thickness of around 2,000 km, and its temperature ranges between 6,000 K and 20,000 K.

### Column C:
- Position: Outermost
- Thickness: Millions of kilometers
- Temperature: 2,000,000 K

These characteristics are associated with the Corona. The Corona is the outermost layer of the Sun's atmosphere, extending millions of kilometers into space, and having a temperature of about 2,000,000 K.

Based on this analysis, the correct names of the Sun's layers described in columns A, B, and C are:

- A: Photosphere
- B: Chromosphere
- C: Corona

Thus, the answer is:
- A: Photosphere; B: Chromosphere; C: Corona

Therefore, the correct choice is:
```
A: Photosphere; B: Chromosphere; C: Corona
```
