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,

The ANS is A, but why it isn't C?

proton-induced x-ray emission' seems to refer to air pollutants, whereas should refer to technique ..misplaced modifier

The opening modifying statement rightly modifies the "technique" and again the "which.... " rightly qualifies the technique.

Moreover, in C "A technique originally developed for detecting air pollutants" before the comma seems to modify "called" rather than the technique.

C is wrong because of the unnecessary comma between pollutants and called.
