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 & 6,000 to 20,000 & 2,000,000 \\
\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 determine the names of the Sun's layers described in columns A, B, and C, we need to match the properties given in the table to the known characteristics of the Sun's layers.

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

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

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

Matching the descriptions with the known layers of the Sun:

- Photosphere:
- Often considered the visible surface of the Sun.
- Has a temperature of approximately 5,500 K.
- Thin layer, about 100 km thick.

- Chromosphere:
- Beneath the corona and above the photosphere.
- Temperatures range from around 6,000 to 20,000 K.
- Thickness of about 2,000 km.

- Corona:
- The outermost layer.
- Extends millions of kilometers into space.
- Extremely high temperatures, around 2,000,000 K.

Based on this information, we can align the columns with the layers:

- Column A matches the Photosphere.
- Column B matches the Chromosphere.
- Column C matches the Corona.

Therefore, the correct answer is:

A: Photosphere; B: Chromosphere; C: Corona
