What is the reason why the edge of the Sun's visible disk is darker than the center?
A)   The gases near the edge are in regions where stronger magnetic fields inhibit the emission of light.
B)   We see more deeply into the Sun near its edge and the gas is cooler at these deeper levels.
C)   We see into shallower layers of the Sun near the edge; the gas is cooler there and so emits less light.
D)   We see into shallower layers into the Sun near the edge, and, because the gas is less dense there, it emits less light.
