Let's evaluate each statement:

I – "Dystopian novels focus on the individuality of the human being, with no dedication to social issues."

- This statement suggests that dystopian novels primarily focus on individuality without addressing social issues. However, this is not an accurate characterization of most dystopian novels, as they often use individual experiences to explore broader social and political issues.

II – "Groups that have been excluded from society for years have got a great part in dystopian novels. They are the ones who are able to observe all that is wrong in the world, and they have got the power to highlight it."

- This statement discusses the role of marginalized groups in dystopian novels, emphasizing their ability to observe and highlight societal issues. This aligns with the common theme of dystopian literature.

III – "The Hunger Games has got no political scope in it, once its narrative focuses on the development of a young adult's life, not on everybody's issues."

- This statement discusses the scope of "The Hunger Games" and suggests that it doesn't have a political focus but rather centers on the development of a young adult's life. However, this statement is not entirely accurate, as "The Hunger Games" does indeed have political and social commentary woven into its narrative.

The correct answer is:

(None of the sentences are correct.)

None of the statements accurately represents the typical characteristics and themes of dystopian novels. Dystopian literature often explores societal and political issues through individual experiences and the actions of marginalized groups, making statements I, II, and III inaccurate in their descriptions.
