The correct answer is A. SUVs are required to have built-in vapor lock systems, which limit the amount of pollution they produce
Step-by-step explanation:
A claim is a statement that expresses the position of someone about some issue, in this case, the claim is about SUVs increasing the pollution levels as a result of their popularity. On the other hand, a counterclaim is a statement that is used to rebut a claim, which means this statement aims at showing what is being claimed might not be true or valid, this also implies the counterclaim should disprove the main point of the claim and provide some evidence or reasons for this. Considering this "SUVs are required to have built-in vapor lock systems, which limit the amount of pollution they produce" is the option that directly responds to the claim because this shows SUVs do not increase pollution as it is stated in the claim and provide reasons for it which in this case is the vapor lock systems of SUVs. This information disproves the claim and deals directly with the main point which is whether SUVs increase pollution or not.
