The complete worked solution.
Every step explained - no skipped algebra.
Jupiter exhibits the fastest rotation among planets, completing one rotation approximately every 10 hours. This rapid spin causes a noticeable flattening at its poles and bulging at the equator, and contributes to complex atmospheric dynamics like multicolored bands and storms, including the Great Red Spot. The quick rotation also influences its strong magnetic field and powerful radiation belts.
Final Answer: Option B - Jupiter
