The question is asking for the best claim restatement. When restating the claim, it is important to clearly state the claim without adding additional elements. The claim should not be restated with the same wording so some detail can be added to clarify but not change the claim. Option A adds the element of the government fixing the problem. This changes the claim so it doesn't work. Option B also changes the claim when it lists the contributors to air pollution. Option D is wrong for the same reasons. Option C is correct because it restates the claim in a different way and the additional detail only clarifies, it doesn't change the claim.
