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

解答：Agreement; Verb form
This sentence presents Newton's explanation of how the gravitational pull of the Sun and other planets affects the motion of individual planets.（也就是说sun和other planets并列） In the underlined section, the focus is on each individual celestial body as a single entity, so pronouns and verbs in this phrase must all be singular.
A. Each is singular, and therefore is not in agreement with the plural pronoun their.
B. The addition of with is unnecessary, creating wordiness; the plural pronoun their doesn't agree with its singular antecedent, each.
这里AB的解答当然可以接受，但我的问题是，不应该是poll of the sun和(poll of) all other planets并列么，按理说后者的of（红标部分）不应该省掉啊？还是说可以理解为sun和other planets共有的poll，所以不用加of？
这个of，究竟是可以省掉呢，还是本来就不应该有？看了一整天的书，实在晕的不行了，诚信求解答，谢谢！
C. The use of the participle contributing makes this ungrammatical.
D. Correct. The singular possessive pronoun its agrees with the singular antecedent, each.
E. The singular subject of the clause each requires a singular verb (contributes) and a singular possessive pronoun (its instead of their).
The correct answer is D.

A/B里面的of不能要的。
之前我刚在某个帖子里回过，其实我们都很明白combination of A and B，而没人说combination of A and of B对不对？因为后面的意思变成A自己的combination，B自己的combination，严重不符逻辑。
这题一样的，我们都只注意到pull of the Sun and... other planets，而忽略了前面的修饰：combined。
加了combined，就变成combined pull of A and B，和combination of A and B是一样的道理。

（弱弱的加一句，其实偶一开始也上当了，唉～）
