Respuesta :
I believe the answer is D. This is due to the author clearly stating that there is obvious differences in opinion about whether or not phones should be used in classrooms or not. It would start of the essay on a basis that acknowledges there are those who believe otherwise before going on with their own opinion.
Here, most appropriate answer would be: "Controversy regarding long-term effects and the abuses of privilege by some students have resulted in a trend toward schools banning cell-phone use in classrooms; however, I believe that this is a matter of personal choice and freedom, and that schools should not ban phones for those who use them responsibly"
In short, Your Answer would be Option D
Hope this helps!
