Some critics claim that the power of the media to impose opinions upon people concerning the important issues of the day is too great. But this is not true. It would be true if on major issues the media purveyed a range of opinion narrower than that found among consumers of media. The fact that this assumption is untrue shows the critics' claim to be false.

Question: Which one of the following most accurately describes a reasoning flaw in the argument?
Options:
A. The argument launches a personal attack against the critics rather than addressing the reasons they present in support of their claim.
B. The argument takes for granted that the media give at least as much exposure as they should to a wide range of opinion on the important issues of the day.
C. The argument takes for granted that if the truth of one claim implies the truth of a second claim, then the falsity of the first claim proves the falsity of the second claim.
D. The argument, instead of providing adequate reasons in support of its conclusion, makes an appeal to popular opinion.
E. The argument takes for granted that it is desirable for a wide range of opinion on the important issues of the day to receive media exposure.
