To build indirect characterization, an author might choose a line of dialogue that reveals something about a character's beliefs, emotions, or personality without directly stating those traits. Among the options provided, the line that most effectively illustrates this is:
“I am very frustrated,” said Simon. “I combed the entire city trying to find that motorcycle helmet, and not one store has it!”
This dialogue showcases Simon's frustration and determination indirectly by illustrating his efforts and emotional state, allowing readers to infer more about his character and his situation.
