Answer:
D. Rejection of traditional beliefs.
Step-by-step explanation:
Probably the most prominent element of literary modernism/modernist literature included the very-much conscious break from traditional techniques and forms, with a shift from linear stories to abstract works. Therefore, your answer would be D. Rejection of traditional beliefs, because modernist literature authors would tend to stray away, or at least rework tradition rather than follow it. This was a result of authors of the horrors of WWI being recognized in a post-war society, the development of industrialism, and the rapid growth of cities. Authors would reflect this disorder and creation of society in their hard-to-follow works riddled with prose and incorrect part of speech.
