At first,the Sun's present-day rotation seems to contradict the prediction of the nebular theory because
A)the theory predicts that the axis of rotation should not be perpendicular to the orbital plane of the planets,but it is.
B)the axis of rotation precesses slowly,which the theory does not predict.
C)the present-day rotation is in the opposite direction from that predicted by the theory.
D)the theory predicts that the Sun should have been rotating fast when it formed,but the actual rotation is fairly slow.
E)the theory predicts that the Sun should not have been rotating when it formed,but the Sun actually rotates today.

Question

The nebular theory predicts that the Sun should have been rotating fast when it formed due to conservation of angular momentum in a collapsing cloud. However, the actual present-day rotation of the Sun is fairly slow, which appears to contradict this prediction.
