A的结构是：
Done, S done, which, VO.
其中两个done都是修饰S，which也修饰S。

C的结构是：
S done, done, which, VO.
首先这个句子结构就不如A选项，主语后面跟了太多的修饰成分。
其次这里which距离要修饰的S非常遥远了，其实在这句话中它的语法作用已经变成修饰 proton-induced X-ray emission

虽然proton-induced X-ray emission和主语a technique实际上是一个东西，但proton-induced X-ray emission是主语的一个【名字】，which意图修饰的对象并不是这个【名字】，而是主语 a technique本身。所以远不如A选项清楚明白。

c 的 called 指代有问题吧违背了原文的意思 -ed的形式一般都是做定语修饰最近的词没法指technique
AC 相比 C主谓间距离有点长了

GMAT的结构：SVO, -ed,这里的-ed修饰前面的词，在选项里就是air pollutants,明显错误，你只要记住这个考点其实这道题很好排除
