This is a familiar space, the tech space <i class="em em-v"></i> everyone wants to hear. so, let's get down to analyzing the options here.

In Option A- Incorrect;
It is not a verifiable fact to say Kahva's product decreased because he didn't advertise on the local radio stations. His numbers might not have increased though but it's certainly not a position of weakness from the author

Option B- Correct
It is most certainly the most accurate prediction in that, Java's coffee rose a magnificent 15% within just three months. Nevertheless, the other 9 coffee shops who advertised on the local station did not witness any increase. It's a position that weakens the conclusion in truth

Option C- Incorrect
Specifically, from the last option in B, it is noticeable that only one out of 9 which represents lesser numbers than the 78% reported. It is thus an incorrect option.

Option D- Incorrect
The local stations having over 10,000 audience does not infer anything substantial herein and unfit to explain why there is only one out of nine in patronage

Option E- Incorrect
The local radio here doesn't concern itself with free sponsors. it is not right to think it's a free sponsor radio
