(A) Originally developed for detecting air pollutants, a technique called proton-induced X-ray emission, which can quickly analyze the chemical elements in almost any substance without destroying it,
(B) Originally developed for detecting air pollutants, having the ability to analyze the chemical elements in almost any substance without destroying it, a technique called proton-induced X-ray emission
(C) A technique originally developed for detecting air pollutants, called proton-induced X-ray emission, which can quickly analyze the chemical elements in almost any substance without destroying it,
(D) A technique originally developed for detecting air pollutants, called proton-induced X-ray emission, which has the ability to analyze the chemical elements in almost any substance quickly and without destroying it,
(E) A technique that was originally developed for detecting air pollutants and has the ability to analyze the chemical elements in almost any substance quickly and without destroying the substance, called proton-induced X-ray

我的思路：A感觉没有谓语；B没A好呢；C,D,E比较感觉E好，因为E把it 用substance代替了，更让人容易明白。就只有E了

答案是A，它的谓语在划线部分之外，就是那is。

B的问题在于句子主语a technique位置太靠后，它前面有两个结构修饰它，现在结构很不协调。

C中called 引导的状语结构没能紧跟它所修饰的词。

D，同C，且which定语从句中也有错。

E 实在错误太多且wordy，一看就可以忽略的选项。
