Explanation

The Sun's layers from inner to outer are: Core → Radiative Zone → Convective Zone → Photosphere (visible surface) → Chromosphere → Corona. The Corona is the outermost layer, visible as a pearly white crown during total solar eclipses. Photosphere (C) is the visible surface, Chromosphere (A) is the thin layer above it.
