I thought B was right during PT, but decided to try negating the answer choices during BR, and got distracted by C.
If you negate C, the gist of it would be that "optimism is NOT better than pessimism," which I think ruins the argument. If optimism is not better than pessimism, then why try to enable young people to believe in a better future? Or is it the "illusory vision" aspect of C that makes this irrelevant?
What am I missing here?
