标题: 求助！prep 07 的136题中一个貌似没有人问过的问题，求解答~~

136. (32028-!-item-!-188;#058&005735)

It seems likely that a number of astronomical phenomena, such as the formation of planetary

nebulas, may be caused by the interaction where two stars orbit each other at close range.

(A) may be caused by the interaction where two stars orbit each other

(B) may be caused by the interaction between two stars that each orbit the other

(D) are caused by the interaction of two stars where each is orbiting the other

(E) are caused by the interaction of two stars orbiting each other
正确答案为E
附上prep语法笔记中的解释：
(C) be because of sth不及动词形式be caused by更有效；
Q:为什么说be because of sth不及动词形式be caused by更有效?be because of 形式对吗?是不是应该是be due to?
求大神指导,谢谢!
