Why not A?

@Patricia-Adekunle, The question asks us to identify the main idea of the passage, in other words, what is the principal argument the author is trying to convey. The author primary purpose is to point out that the critics wrongfully blame the failures of modern architecture on the ideals of its founder - Otto Wagner as his vision was more complex. While (A) correctly restates one of the ideas expressed in the passage, it is not the main idea, similarly to (E). Does this make sense? Let me know if you have any further questions
