Originally developed for directing air pollutants, a technique called proton-induced X-ray emission, which can quickly analyze the chemical elements in almost any substance without destorying it, is finding uses in medicine, archaelogy, and criminology.
(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) Orignially 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
(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,
OA:A
In reply to the post above Ron replies that:
nouns that are modified by prepositional phrases can still be the referent of 'which' even if they are a few words distant from it.

If not then which is the preposition referred to by Ron?
