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.

• Amay be caused by the interaction where two stars orbit each other
• Bmay be caused by the interaction between two stars that each orbit the other
• Care because of the interaction between two stars that orbit each other
• Dare caused by the interaction of two stars where each is orbiting the other
• Eare caused by the interaction of two stars orbiting each other
  

求解选项C为何不能作为正确选项？

(C) be because of sth不及动词形式be caused by更有效；each…the other搭配错误；where用法错，
原因与A选项相同。
prep笔记里有解释的呀

这解释一点不对，哪里来的the other，题目中是each other，也没有where而是用的that修饰前面的stars。这纯复制黏贴闹哪样？
