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

答案是D  我选定是C  为什么没有of which 呢？不是指代之前的sun and planets 吗？

把SC发到逻辑区了。

of后要接宾格代词them，each of them contributing...

each of which是restrictive clause 后面不能接 contributing，必须接完整谓语 contributes，不然构成fragment。

each contributing according to its...是 absolute construction，apppsitive pronoun+present participle是可以的。
