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, is finding uses in medicine, archaeology, 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) 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,

(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,
Correct : Inferred meaning is correct. Sentence is grammatically correct

(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
Incorrect :"having the ability" induces error

(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,
Incorrect : "called proton-induced x-ray emission" has no meaning in the sentence.

(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,
Incorrect : same as C

(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,
Incorrect : meaning changes also "called proton-induced x-ray emission" is improper
I will go with A

I would choose A

A- Correct

B- "having the ability" is a misplaced modifier

C- I'm actually not sure if this is wrong and if it is I dont' know the exact reason, it just didn't sound as good as A to me

D- "and without destroying it" is awkward and wrong

E- same as D

I think why C is wrong because "technique" should modify "proton-induced x-ray emission" but instead it is modifying "CALLED proton-induced x-ray emission"

Whereas in A, it removes the ambiguity by writing the sentence completely "a technique called proton-induced x-ray emission"
