In what way does Oedipus show responsibility throughout the play?

Oedipus demonstrates responsibility by actively seeking to uncover the truth about Laius's murder in order to save Thebes from the plague that afflicts the city. This quest shows his commitment not only to his role as king but also to the well-being of his people. By taking charge of the investigation, he embodies the qualities of a responsible leader who prioritizes the needs of the city and its citizens over his own personal safety or reputation. His determination to find the murderer reflects a deep sense of duty and accountability, as he believes that understanding the cause of the city's suffering is essential for restoring order and health.

This action contrasts with other choices that suggest avoidance or reliance on others, which do not align with Oedipus's proactive approach to solving the crisis facing Thebes.
