Thanks for the question! It’s not (E) because the argument never says it’s not possible to compare yourself to those you think are equals. So it’s a mischaracterization of what’s going on in the argument, and so can’t be a flaw. ?It’s not (B) because the conclusion doesn’t talk about benefits, it talks about potential bad things tat might happen.
(D) is correct because the argument basically ignores the possibility that something else results in the inability to be self-accepting/accepting of others.
Hope this helps! Feel free to ask any other questions that you might have.
