Respuesta :
B. is the best and only answer for the question because it is a counterclaim to the claim. hope this helps :)
The best counterclaim for this claim is B: Financial aid for college students should be based on each student's financial need.
Explanation: This sentence supports that the criterion for financial aid should be the financial need of each student instead of the academic achievement.
Sentence A is irrelevant because it talks about the percentage of students who receive financial aid and not about the criterion for offering it. Sentences C and D seem to agree with the initial statement and so they cannot be a counterclaim.
