(A) Information services are accessible to enough people to ensure that political advocacy groups can use these services to reach as large a percentage of the public as they could through traditional news sources. - Incorrect. Accessibility is not a question here, argument is about "Balanced" political views.

(B) People could get a thorough understanding of a particular political issue by sorting through information provided by several traditional news sources, each with differing editorial biases. - Incorrect. It helps the traditional news not the IS, argument is about "Balanced" political views not how people understand news by sorting the traditional news.

(C) Information on political issues disseminated through information services does not come almost entirely from advocacy groups that share a single bias. - Correct. It clearly says that the IS doesn't come from single bias group, its more balanced. If we negate this option, "the IS is coming from biased group" then the argument falls apart i.e, the IS is no balanced.

(D) Traditional news sources seldom report the views of political advocacy groups accurately. - Incorrect. Again, the question is about Balanced political group not about traditional news accuracy.

(E) Most people who get information on political issues from newspapers and other traditional news sources can readily identify the editorial biases of those sources. - Incorrect. Though this option mentions bias but it doesn't focus on IS it rather tells us about traditional news.
