The correct answer is B. Making people vote will result in uneducated voters who vote randomly
Explanation:
A counterclaim is a claim or statement that rebuts or goes against a claim, in this case, the main idea of the claim proposed is that all Citizens from the United States should vote in every election, probably because an important percentage of citizens do not participate in election and the author of this considers the most important is all citizens participate. However,all citizens participating in the elections might not be that positive as this might not mean responsible participation, in this way option B "Making people vote will result in uneducated voters who vote randomly" is a counterclaim because it shows the first idea of making everybody vote has negative implication and thus it is not as valid as it seemed, as this idea rebuts the first idea it is classified as a counterclaim.
