How Does One Describe the Rotation of the Sun

How does one describe the rotation of the Sun?

A) The Sun rotates as a single rigid object, much like Earth.
B) The equatorial region of the Sun rotates faster than the polar regions, and this differential rotation extends all the way through the core.
C) The equatorial region of the Sun rotates more slowly than the polar regions, and this differential rotation extends all the way through the core.
D) Differential rotation extends only partway into the Sun. The core rotates as a rigid body.
