realistic versions

The thesis Julio presents effectively is (B) Many folk tales are not happy children's stories but dark, realistic tales.

Explanation:

Julio tells us tales that are often harmless and enjoyed by kids. The tales are filled with magic in which good wins and evil is always defeated at the end.

But the "original folk tales" represent the reality of life. They show about hunger, death and everyday struggles of people. They show real feelings of people. Julio says that all these original tales are always true and dark but some of them might be. Example of such story is when Cindrella's step sisters cut their toe finger to fit in the shoe.
