I would say A. because during the solar eclipse you cannot see the suns Photosphere at all, and the corona is the light that emits around the moon during the eclipse.
The corona of the sun is only visible during a solar eclipse, meaning you can't see it on a normal day. The photosphere is the deepest layer of the sun. The chromosphere is the layer outside of the photosphere. I would say the answer is B.
Hope this helps! I would greatly appreciate a brainliest! :)
