C) It incorrectly assumes that popularity equates to moral correctness.
Explanation:
A fallacy is an argument that is not correct but that might persuade people to believe it by appearing to be a good reasoning. According to this, the reasoning is fallacious in this statement because it incorrectly assumes that popularity equates to moral correctness. This is the answer because the statement indicates that as the reality is popular, it is not corrosive and decadent and this is an invalid argument because if a program is popular, this doesn't mean that it is morally correct. However, this may be an argument that people might believe.
