求解答一个语法问题

哑舍

The Nobel Prize in chemistry was awarded to three scientists for their discovery that plastic can be made electrically conductive—an advance that has led to improvements in film, television screens, and windows.

A. that plastic can be made electrically conductive—an advance that has led
B. that plastic can be made electrically conductive—this advance leading
C. that plastic can be made to be electrically conductive, and this advance led
D. of plastic's ability to be made electrically conductive, with this advance leading
E. of plastic being able to be made electrically conductive—an advance that has led
这道题做的时候选对了选了A，但是对B的分析不太清楚，破折号加this advance leading的这个用法错误是在哪呢？求解答或者有看到关于选项B比较好的解释的，如ron的求链接，自己木有搜到啊

B中的this不可以指代整个句子~

我猜测。。。。可能是this advance前面需要有一个blah blah advance。。。但是似乎并没有。。。而且使用leading会有正在发生的意思，但是显然题目是想要表达这个advance的影响，所以完成时更合适一些？

关于B
大神是这么说得：

you can't start with 'this advance' unless you're writing a new independent clause (as you would if you were following a coordinating conjunction such as 'and', 'but', etc.) if you're going to use a modifier like this, it should start with 'AN advance' (as does choice A).
