Which of the following, if true, is most damaging to the position of the cable-television spokesperson?

(A) Consumers who do not own television sets are less likely to be influenced in their purchasing decisions by television advertising than are consumers who own television sets.
(B) Subscriptions to cable television include access to some public-television channels, which do not accept advertising.
(C) For locations with poor television reception, cable television provides picture quality superior to that provided by free television.
(D) There is as much advertising on many cable-television channels as there is on "free" television channels.
(E) Cable-television subscribers can choose which channels they wish to receive.

Please provide a good explanation to this question.

Which of the following, if true, is most damaging to the position of the cable-television spokesperson?

(A) Consumers who do not own television sets are less likely to be influenced in their purchasing decisions by television advertising than are consumers who own television sets. [It is implying that the advertisement influences, to some degree, the purchasing decisions of a consumer. It is a strengthener]
(B) Subscriptions to cable television include access to some public-television channels, which do not accept advertising. [This options shows that cable tv is better. Sort of a strengthener]
(C) For locations with poor television reception, cable television provides picture quality superior to that provided by free television. [ Picture quality is out of scope]
(D) There is as much advertising on many cable-television channels as there is on "free" television channels. [ Cable guy says that costly advertising on "free" tv is not good for consumers as consumers will indirectly pay for those ads. If there is as much advertising on the cable tv as there is on "free" tv, then there is clearly no difference between cable tv and "free" tv. Hence this argument is hurting the cable guy's argument]
(E) Cable-television subscribers can choose which channels they wish to receive.[ Not relevant]
