标题: OG13 106 关于v-ing短语修饰对象的新问题

关于v-ing修饰对象的问题讨论的很多了，在本题遇到了新问题：
关于答案B的解释是：second modifier (having...) actually modifies the first modifier. 按照之前的理解，v-ing可以修饰之前的名词，但是按照本题关于B的解释，貌似还可以修饰之前的短语，而不仅仅是名词。
已经被分词修饰搞得比较混乱了，求解答

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,

Rhetorical construction
The original sentence successfully avoids the problems that may occur in a long sentence with multiple modifiers. The sentence opens with the modifier originally developedfor detecting air pollutants. This participial phrase is immediately followed by the word technique that it modifies; technique is in turn followed by the phrase called proton-induced X-ray emission. Finally, the nonrestrictive clause which ... destroying it is correctly placed next to emission and set off from the rest of the sentence by a pair of commas.
A    Correct. The modifiers are all correctly placed and punctuated; the meaning is clear.
B    Placement of two long modifiers at the beginning of the sentence is awkward and makes it difficult to locate the subject; second modifier (having...) actually modifies the first modifier.
C    Called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas; relative clause . introduced by which incorrectly and illogically modifies emission.
D    Called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas; relative clause introduced by which incorrectly and illogically modifies emission; has the ability to is wordy.
E    Called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas; has the ability to is wordy.

我也是有这样的问题
这里HAVING修饰前面的名词pollutants.
但我一直以为，ving 只修饰前面的主语或者整个句子。难道这里前面的主语是pollutants?
晕了
