Please help I am unable to find the answer

The most famous protagonists in literature have always been at odds with societal norms, but it has been increasingly fashionable for postcolonial literature to glorify these iconoclastic protagonists much more than any previous genre of literature has. By presenting these characters as being worthy of emulation, postcolonial authors subtly endorse their outsider ethos and may convince their readers to adopt it. Thus, postcolonial literature can be harmful to at least some of its readers, and thereby to society itself.

Which of the following is an assumption on which the argument above depends?
A. Some protagonists from earlier literature were better role models than any found in postcolonial literature.
B. It is beneficial for some readers to avoid adopting an outsider ethos or to avoid emulating iconoclasts.
C. Postcolonial protagonists who adopt an outsider ethos will harm readers more now than if they did adopt that ethos.
D. The aesthetic merit of some literary works cannot be judged without considering their moral implications.
E. Postcolonial literature presents a greater number of outsider characters than did the literature of earlier eras.

Thanks.
