b. The attitude and motivations of the characters.
Explanation:
A theme is not defined by the quality of the story. Stories might have different themes or equal themes and be good or bad. Also, the author's prejudices might influence the story, but not necessarily the theme as well. Authors with the same kind of prejudice might right horror stories or dramas and insert their point of view in stories about survival or family. Same goes to style. The theme is determined by what envolves and guides the story and characters and how the characters react to it.
I think they are watching a match. They do not have enough money to buy the tickets. So, they are watching the match by climbing on their cycles, because the stadium boundary wall is very high.
