"B. The radiant sun.
The Sun, like all stars, is a huge plasma ball of very high density and temperature. It consists almost entirely of hydrogen, with a small component of helium and all other elements in smaller proportions.
Although the plasma in the deep interior of the Sun has a chaotic movement, towards its surface and on it the movements of the plasma are already more ordered.
