A. Many students have jobs, and an extended school day would interfere with their work schedules.
This is a reasonable counterclaim to this claim. There is a direct cause and effect between extending the school day and student work schedules. Option B does not have a direct interaction between the two topics. The extended school day has nothing to do with the curriculum the teachers are teaching. Option C is also not a reasonable counterclaim, because it only is a problem if the school day started earlier. An easy rebuttal would be that the school day would be extended into the afternoon, not the morning. Option D is completely irrelevant to the issue.
