The correct answer is B) The counterclaim is supported by strong evidence.
Even if the claim is valid (which excludes option A), it does not offer other evidence than the author's perception that crowds disturb the city and looks for the audience to agree on that. This lack of strong evidence supporting the author's claim also invalidates option C.
On the other hand, there is a counterclaim (excluding option D) that actually offers strong evidence supporting it. The fact that the festival attracts lots of tourists and generates revenue for the city, including the local businesses that support the festival, is strong evidence that supports the claim that the festival should be maintained.
So the only correct answer is option B.
