106. Originally developed for detecting airpollutants, a technique called proton-induced X-ray emission, which can quicklyanalyze the chemical elements in almost any substance without destroying it, is finding uses in medicine, archaeology, andcriminology. (A) Originally developed for detecting airpollutants, a technique called proton-induced X-ray emission, which can quicklyanalyze the chemical elements in almost any substance without destroying it, (B) Originally developed for detectingair pollutants, having the ability to analyze the chemical elements in almostany substance without destroying it, a technique called proton-induced X-rayemission (C) A technique originally developed fordetecting air pollutants, called proton-induced X-ray emission, which canquickly analyze the chemical elements in almost any substance withoutdestroying it, (D) A technique originally developed fordetecting air pollutants, called proton-induced X-ray emission, which has theability to analyze the chemical elements in almost any substance quickly andwithout destroying it, (E) A technique that was originallydeveloped for detecting air pollutants and has the ability to analyze thechemical elements in almost any substance quickly and without destroying thesubstance, called proton-induced X-ray emission,
求教，og在C.D.E选项中都说：called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas.
我想知道为什么那么多的修饰成分，一定就called proten-induced X-ray emission要紧邻，其他都不用呢？
求NN解答，感激不尽！！！
