她去年9月来中国之前没来过中国.
去年9月已经是过去的时间了,而在去年9月之前,就是表示“过去的过去”
所以用过去完成时
因为后面有last september这个时间状语，它是一般过去时的时间状语，所以能用B过去完成时的
过去的过去用过去完成时态
希望我的回答能够帮到你，望采纳！
祝你学习进步，天天快乐。O(∩_∩)O

从句last september，可以看出是过去时，所以用came，主句就是过去的过去，就用过去完成时
从before可以看出 visit 是先于come 发生的过去动作， 过去的过去要用过去完成时
注意： B 也对， 因为before 已经表明时间的先后关系，在英语中，此时可以用一般过去时代替过去完成时
came 是过去发生，而前面的动作在came 之前，所以用过去完成
