The answer is D. The author supplies a rebuttal that quotes more current research. He quotes two sources, an article from 2009 that argues that cell phones cause too many distractions (the counterclaim that he wishes to disprove) and a poll from 2013 that reveals that 67% of high school instructors now encourage students to use phones in the classroom setting. The  second source serves as a counterpoint to the first, since it shows that high school instructors now view phones as a teaching aid instead of a source of distraction.
