In surprising medical news, scientists investigating long-term effects of stroke are reporting that injury to a specific part of the brain, located behind the ear, can instantly and permanently break a smoking habit.

brain, located behind the ear, can instantly and permanently break the habit of smoking
brain located behind the ear, can instantly and permanently break a smoking habit
brain, the one located behind the ear, can instantly and permanently break the habit of smoking

The answer is A and I got it wrong. I chose B. From the explanation, A turns out to be correct as B creates run-on. My idea of selecting B was that we need to point to the specific part of the brain, injury to which can cause the effect. Can anyone explain why the "located behind the ear" is parenthetical. Ideally, we need this phrase to point to pinpoint to the specific part of the brain. So, I think this phrase is needed to identify the brain's part and thus a restrictive phrase.

Even I got it wrong. I thought with the presence of comma, phrase "located behind the ear" is modifying the word (in this case 'brain') just before comma.

So if you say A is correct, than I can infer that the "presence of comma" is different from "presence of which".
