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
emission,

My Question is OG says which in A clearly refers to emission, whereas I ruled out A thinking which refers to technique. Please clarify this doubt.

Just reiterating what Frankenstein said, and hopefully with some emphasis and authority:

Reflexive pronouns like "which", "where", and "who" can only modify the word that comes immediately next to it. It's one of the clearer, more knee-jerk rules on the GMAT so it should be a pretty nice asset for you. If you see a modifier beginning with "which" or another reflexive pronoun, look at the word immediately next to it...if it can't logically be the correct noun or noun phrase, eliminate it immediately!
