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.

\begin{tabular}{|l|l|l|l|}
\hline & \multicolumn{1}{|c|}{ A } & \multicolumn{1}{c|}{ B } & \multicolumn{1}{c|}{ C } \\
\hline Position & Lowest & Middle & Outermost \\
\hline Thickness & [tex]$100 \text{ km}$[/tex] & [tex]$2000 \text{ km}$[/tex] & Millions of kilometers \\
\hline Temperature & [tex]$5{,}500 \, \text{K}$[/tex] & [tex]$6{,}000 \text{ to } 20{,}000 \, \text{K}$[/tex] & [tex]$2{,}000{,}000 \, \text{K}$[/tex] \\
\hline
\end{tabular}

What are the names of the Sun's layers described in columns [tex]$A$[/tex], [tex]$B$[/tex], and [tex]$C$[/tex]?

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 need to interpret the given data in the table and match it with the correct names of the Sun's atmospheric layers.

Let's outline the information provided:

- Position:
- Column A: Lowest
- Column B: Middle
- Column C: Outermost

- Thickness:
- Column A: 100 km
- Column B: 2000 km
- Column C: Millions of kilometers

- Temperature:
- Column A: 5,500 K
- Column B: 6,000 to 20,000 K
- Column C: 2,000,000 K

With this information, we need to match each column to the correct name of the Sun's layers.

### Layers of the Sun:

1. Photosphere:
- Position: Lowest layer visible from Earth.
- Thickness: Approximately 100 km.
- Temperature: About 5,500 K.

2. Chromosphere:
- Position: Middle layer.
- Thickness: Approximately 2000 km.
- Temperature: Ranges from around 6,000 to 20,000 K.

3. Corona:
- Position: Outermost layer.
- Thickness: Extends millions of kilometers into space.
- Temperature: Reaches about 2,000,000 K.

### Matching the Columns to the Layers:

- Column A:
- Position: Lowest.
- Thickness: 100 km.
- Temperature: 5,500 K.
- Therefore, Column A corresponds to the Photosphere.

- Column B:
- Position: Middle.
- Thickness: 2000 km.
- Temperature: 6,000 to 20,000 K.
- Therefore, Column B corresponds to the Chromosphere.

- Column C:
- Position: Outermost.
- Thickness: Millions of kilometers.
- Temperature: 2,000,000 K.
- Therefore, Column C corresponds to the Corona.

Given these matches, the correct names of the Sun's layers described in columns A, B, and C are:

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

Thus, the correct answer from the given options is:
A: Photosphere; B: Chromosphere; C: Corona.

Therefore, the correct choice is:

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