OFFICIAL EXPLANATION:

(Distinguish X from Y) Whenever you find the word “distinguish” in the given sentence, you should be alerted about the possibility of a wrong preposition being used with it. The correct phrase involving this word is “distinguish X from Y.” The given sentence uses this correct phrase, and is probably the answer.

Now, scanning the answer choices, we find that they all result in wrong phrases “distinguish X and Y.”

“distinguish between X or Y” and “distinguish among X or Y.”

So, we can confirm (A) itself as the answer.
