Which statement describes the motion of the sun? a: the sun rotates at the same rate throughout. b: the sun does not rotate at its poles. c: different parts of the sun rotate at different rates. d: the sun does not rotate at its equator.

If I get this wrong please don't judge:

C. Different parts of the sun rotate at different rates.

The sun isn't a solid, its a big ball of gas.

C. Different parts of the sun rotate at different rates.

Explanation:

The Sun rotates on its axis. The spin rate is different at different parts of it. This is because Sun is not a solid. It is a gas giant. Its energy  or radiation is all derived from thermonuclear reactions like the proton proton cycle and the Carbon Nitrogen cycle  that happen inside it.

Unless it is a solid object, something like the Earth, all parts of it cannot spin at the same rate.
