A. Criticizing a government, person, or institution
The key words in the question here are "higher purpose". Might an author retell a classic story or share the lives of ordinary people, yes. However, these do not accomplish a higher purpose. When undertaking a higher purpose, the story must do more than just tell a good story. There needs to be a second level of meaning or understanding. Often author's use literature as a way of criticizing powerful entities like the government, people, or institutions because they can remain safe and deny any harmful intent even if it isn't so.
