Final answer:
The sun rotates more slowly at its poles due to differential rotation.
Step-by-step explanation:
The best description of how the sun rotates is option B: The sun rotates more slowly at its poles. The sun is not a solid object like Earth, so different parts of the sun rotate at different speeds. The equator of the sun completes one rotation faster than the poles, resulting in a differential rotation where the equator rotates faster than the higher latitudes.
