C Correct answer
Explanation

The corona is the outermost layer of the Sun's atmosphere, extending millions of kilometers into space. It consists of extremely hot plasma (temperatures around 1-3 million K) and is visible during a total solar eclipse as a pearly white crown. The photosphere is the visible surface, the chromosphere is a thin layer above it, and the ionosphere is Earth's atmospheric layer, not the Sun's.
