请教：关于which指代的问题

which 究竟是就近指代还是按逻辑意思指代？

比如下面这题（OG11-105），选项A,C的which指代的不一样吗？

谢谢！

(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,（A）

(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 emission,

新东方课堂记录：

which尽量就近指代：

主+谓+宾, which...：因为有宾语，which就不会去指主语

如果上述情况中的宾语为：名词1+of+名词2，which通常就近指名词2，但也可以指名词1，此时要通过语法（如单复数）避免歧意

你说的这道题里面，which从句是修饰emission而不是修饰technique的，A和C中，在这一点上没有错误

但是大全上对这两个答案which指代问题的讲解是不一样的。

A：The modifiers are all correctly placed and punctuated.

C: relative clause introduced by which incorrectly and illogically modifies emission.

这是怎么回事呢...
