Counterarguments function to invalidate the prior claims or arguments proposed in an essay, paper, or text. Thus, they need to be addressed carefully by offering sufficient evidence to substantiate your actual claim or idea which is here about 'the importance of immigration reform'. In the given example, paragraph 3 aptly addresses the counterclaim('Immigrants drain resources from American citizens') by proposing relevant factual evidence that 'immigrants contribute to the U.S. economy' that strengthens the original claim of the author. Thus, <u>option B</u> is the correct answer.
This would be a good place to place a counterclaim where your claim is "Immigrant contribute to the US economy" so you can show your unbiased and state "Yeah they effect our economy but sometimes in a bad way as they can drain us of our resources and negatively affect it"
