单选题 Many state legislatures are considering proposals to the effect that certain policies should be determined not by the legislature itself but by public referenda in which every voter can take part. Critics of the proposals argue that the outcomes of public referenda would be biased, since wealthy special-interest groups are able to influence voters' views by means of television advertisements.
Which of the following, if true, most strengthens the critics' argument?

A、 Many state legislators regard public referenda as a way of avoiding voting on issues on which their constituents are divided.
B、 During elections for members of the legislature, the number of people who vote is unaffected by whether the candidates run television advertisements or not.
C、 Proponents of policies that are opposed by wealthy special-interest groups are often unable to afford advertising time on local television stations.
D、 Different special-interest groups often take opposing positions on questions of which policies the state should adopt.
E、 (E) Television stations are reluctant to become associated with any one political opinion, for fear of losing viewers who do not share that opinion.
