The correct answer is B) Teachers are the best judges of how much homework is necessary.
Explanation:
The purpose of a counterclaim is to present an opposite position about a specific situation or issue. In the case presented, the claim focuses on stating homework should be regulated by law. On the other hand, the first counterclaim states homework should be established by students. This means the main focus of the claim and counterclaim is who or what assigns and regulates homework.
According to this, the best option for a counterclaim is "Teachers are the best judges of how much homework is necessary" because this presents an opposite position about who should assign homework as in this case, it purposes teachers should do it rather than the law.
