Saturn's Rotation Rate Is Very Fast but Slower Than Jupiter's

Saturn's rotation rate is very fast but slower than Jupiter's. The wind speed at Saturn's equator, compared to the wind speed at Jupiter's equator, is:

A) smaller than Jupiter's because Saturn's rotation rate is less.
B) smaller than Jupiter's because Saturn's mass is less.
C) smaller than Jupiter's because of Saturn's smaller radius.
D) larger than Jupiter's for reasons not completely understood.
