The correct response is:
The justice dealt to Nolan serves as a valuable lesson for him, as he is made to confront his disloyalty to his country.
This option effectively captures the theme of justice in the play by highlighting how Nolan's punishment leads him to reflect on his actions and feelings toward his country. Through his confrontation with his own disloyalty, the narrative conveys that justice is not merely about receiving consequences but also about personal growth and understanding the significance of loyalty. While other options discuss aspects of injustice or bitterness, this response aligns more closely with the idea that justice can serve as a transformative experience for the individual involved.
