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 crimi-
nology.

‍air pollutants, called proton-induced x-ray
‍emission, which can quickly analyze the

A and D are close, Which in A modifies technique and is correct.

(E) cannot be correct because "called proton-induced x-ray..." seems to refer to "...the substance"

(A) is the best choice.

what's wrong with C? It doesn't seem to distort the meaning, does it?

"which" is a non-restrictive noun which gives non-essential additional information on the noun preceding the comma. The preceding noun here is "proton-induced x-ray emission" and it clearly is not what is performing the action of analyzing chemical elements...

Basically "which can quickly analyze the chemical elements in almost any substance without destroying it" is a misplaced modifier
