GWD-29-Q26 看过历史帖子还是有疑问

姿姿不倦

In his experiments with gravity, Isaac Newton showed how the motion of each planet in the solar system results from the combined gravitational pull of the Sun and of all the other planets, each contributing according to their mass and distance from the others.
A.    of all the other planets, each contributing according to their
B.    of all the other planets, with each of them contributing according to their
C.    all the other planets, each of which contributing according to its
D.    all the other planets, each contributing according to its
E.    all the other planets, each of which contribute according to their

答案选D。我知道后面那个是独立主格结构； each contributing according to its， 这里的each是指前文“ how the motion of each planet ”的planet还是“ all the other planets”的planet？
可能我句意理解不是很清楚的缘故。。希望懂的TX能帮忙解答一下，最好讲解下这个选项的意思。

我觉得是 the Sun and all the other planets 全部， 这里contributing的“潜在”对象该是 pull

each应该指是all the other planets”的planet

首先each通常就近修饰前面的名词；
