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

\begin{tabular}{|l|l|l|l|}
\hline \multicolumn{1}{|c|}{ A } & \multicolumn{1}{|c|}{ B } & \multicolumn{1}{c|}{ C } \\

Let's analyze the data presented about the Sun’s layers and match it with the correct names.

1. Position:
- The layer labeled `A` is at the lowest position.
- The layer labeled `B` is at the middle position.
- The layer labeled `C` is the outermost layer.

2. Thickness:
- The thickness of layer `A` is 100 km.
- The thickness of layer `B` is 2000 km.
- The thickness of layer `C` is measured in millions of kilometers.

3. Temperature:
- The temperature of layer `A` is 5,500 degrees.
- The temperature of layer `B` ranges from 6,000 to 20,000 degrees.
- The temperature of layer `C` is 2,000,000 degrees.

Let's match these characteristics with the known features of the Sun's layers:

- Photosphere:
- Position: It's the lowest atmospheric layer.
- Thickness: Approximately 100 km.
- Temperature: Around 5,500 degrees.

- Chromosphere:
- Position: It lies above the photosphere, making it the middle layer.
- Thickness: Roughly 2000 km.
- Temperature: Between 6,000 and 20,000 degrees.

- Corona:
- Position: It's the outermost layer of the Sun.
- Thickness: Extends for millions of kilometers.
- Temperature: About 2,000,000 degrees.

From this information, we find the following matches:
- Layer `A` corresponds to the Photosphere (lowest position, 100 km thick, 5,500 degrees).
- Layer `B` corresponds to the Chromosphere (middle position, 2000 km thick, 6,000 to 20,000 degrees).
- Layer `C` corresponds to the Corona (outermost position, extends for millions of kilometers, 2,000,000 degrees).

Therefore, the named layers in columns [tex]\( A, B, \)[/tex] and [tex]\( C \)[/tex] are:
- [tex]\( A \)[/tex]: Photosphere
- [tex]\( B \)[/tex]: Chromosphere
- [tex]\( C \)[/tex]: Corona

Thus, the correct answer is:
[tex]\[ \boxed{\text{A: Photosphere; B: Chromosphere; C: Corona}} \][/tex]
