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 correct naming of the Sun's layers described in columns A, B, and C, we need to match the given characteristics (Position, Thickness, and Temperature) of each layer to their known scientific names.

Given Data:
- Position: Lowest, Middle, Outermost
- Thickness: [tex]\(100 \, \text{km}\)[/tex], [tex]\(2000 \, \text{km}\)[/tex], Millions of kilometers
- Temperature: [tex]\(5500 \, \text{K}\)[/tex], [tex]\(6000 \, \text{K} \, \text{to} \, 20000 \, \text{K}\)[/tex], [tex]\(2000000 \, \text{K}\)[/tex]

1. Layer A:
- Position: Lowest
- Thickness: [tex]\(100 \, \text{km}\)[/tex]
- Temperature: [tex]\(5500 \, \text{K}\)[/tex]

This description matches the Photosphere, which is the lowest layer of the Sun’s atmosphere and has a temperature around [tex]\(5500 \, \text{K}\)[/tex].

2. Layer B:
- Position: Middle
- Thickness: [tex]\(2000 \, \text{km}\)[/tex]
- Temperature: [tex]\(6000 \, \text{K} \, \text{to} \, 20000 \, \text{K}\)[/tex]

This description matches the Chromosphere, which lies above the Photosphere and has a temperature range from [tex]\(6000 \, \text{K}\)[/tex] to [tex]\(20000 \, \text{K}\)[/tex]. It is thicker than the Photosphere.

3. Layer C:
- Position: Outermost
- Thickness: Millions of kilometers
- Temperature: [tex]\(2000000 \, \text{K}\)[/tex]

This description matches the Corona, which is the outermost layer of the Sun’s atmosphere and has a temperature of a few million degrees Kelvin.

Based on these observations, the correct matching of the Sun's layers to the table columns is:

Column A: Photosphere
Column B: Chromosphere
Column C: Corona

Hence, the correct answer is:

A: Photosphere
B: Chromosphere
C: Corona

The option that corresponds to these names is:

A: Photosphere; B: Chromosphere; C: Corona

Therefore, the answer is:

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