Answer :
Sure, let's identify the names of the Sun's layers described in columns A, B, and C based on their descriptions.
From the table provided:
1. The layer in column A is at the lowest position, has a thickness of 100 km, and a temperature of 5,500. This matches the characteristics of the Photosphere.
2. The layer in column B is in the middle position, has a thickness of 2000 km, and a temperature range of 6,000 to 20,000. These characteristics match the Chromosphere.
3. The layer in column C is at the outermost position, has a thickness in the millions of kilometers, and a temperature of 2,000,000. This description matches the Corona.
Based on these observations, the names of the Sun's layers described in columns A, B, and C are:
A: Photosphere
B: Chromosphere
C: Corona
So, the answer is:
A: Photosphere; B: Chromosphere; C: Corona
