D Correct answer
Explanation

Jupiter has the shortest day of all planets, rotating once every ~9.9 hours. Its rapid spin creates powerful storms and gives it an oblate shape. Mercury rotates slowly (59 Earth days), Venus extremely slowly (243 days retrograde), and Earth in 24 hours.

AI explanation

Jupiter is the fastest-rotating planet in the solar system, completing a full rotation in under 10 hours despite being the largest planet. This rapid spin is largely why Jupiter is visibly flattened at its poles and bulges at its equator. Earth, Venus, and Mercury all rotate far more slowly by comparison (Venus in particular rotates extremely slowly, taking longer than its year).
