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 & 100 km & 2000 km & Millions of kilometers \\
\hline
Temperature & 5,500 K & 6,000 to 20,000 K & [tex]$2,000,000$[/tex] K \\
\hline
\end{tabular}

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 identify the names of the Sun's layers based on their positions, thickness, and temperature, we must match the given characteristics to what we know about the Sun's layers. Here's a detailed analysis of each layer based on the provided information:

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

This corresponds to the Photosphere. The photosphere is the layer we see as the visible surface of the Sun and has an approximate temperature of 5,500 K. It is also the lowest layer in comparison to the other atmospheric layers.

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

This corresponds to the Chromosphere. The chromosphere lies above the photosphere and below the corona. Its temperature ranges between 6,000 and 20,000 K, which fits the description given.

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

This corresponds to the Corona. The corona is the outermost layer of the Sun's atmosphere, extending millions of kilometers into space. Its temperature reaches up to a million degrees Kelvin, far hotter than the other layers.

Hence, the correct identification of the Sun's layers is:
- Column A: Photosphere
- Column B: Chromosphere
- Column C: Corona

So the correct option is:

A: Photosphere; B: Chromosphere; C: Corona
