Why is C incorrect?

@Shiyi-Zhang, Happy to help. This is a strengthen with a necessary premise question. We're looking for an answer choice that, if false, would make the argument fall apart. The answer choice must be true in order for the argument to make any sense. The stimulus concludes that political opinions and analyses aired on talk shows are typically bland and innocuous. The stimulus says that this is because TV stations are driven by the same economic forces as sellers of tangible goods. The TV stations desire a large audience and, as a result, they have TV shows that provide appeal to lots of people. In reading the stimulus, we see that there's a large gap between the premises and the conclusion. We're told in the premises that TV stations try to appeal to the masses, and the conclusion says that political opinions on these stations will, therefore, be bland. The correct answer choice will likely have something to do with this gap. (C) says, "Each television viewer holds some opinion that is outside the political mainstream, but those opinions are not the same for everyone" The negation of (C) is that not every television viewer holds some opinion that is outside the political mainstream, but those opinions are not the same for everyone. If (C)'s negation were true, the argument is not wrecked. Regardless of whether (C) is true or false, neither scenario helps us to bridge the gap between TV stations providing people with what they want and the political opinions on shows being bland. We can get rid of this choice. (B) says, "There are television viewers who might refuse to watch television talk shows that they knew would be controversial and disturbing" (B)'s negation is that there are no television viewers who might refuse to watch television talk shows that they knew would be controversial and disturbing. If (B)'s negation were true, then the argument in the stimulus would fall apart. This means that (B) must be true in order for the argument to stand a chance. If people were fine with watching controversial things, then why would the political opinions be bland and innocuous? In order for the stimulus to make sense, there must be some people that wouldn't watch shows with controversial opinions. This is the correct answer choice. Does this make sense? Let us know if you have any more questions!
