Which is an example of a plasma that occurs in nature?

A burning tree.

The radiant sun.

A melting candle.

An electric current.

"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. Below the surface of the Sun the plasma circulates up and down, forming cells called convection, and on the surface and already in its atmosphere the movements of the plasma are strongly controlled by local magnetic fields of varying intensity and varied structure."
