When Romeo says "my sin is purged," what does he mean

i would say the answer is erm c but if you dont agree im so sorry

there is no short story here so that i can answer the question.

i believe it is the first choice (1.)

because the major theme is(“both the wild and civilization have rules.”)

and also as u said,( based on what buck learns within the call of the wild, "both the wild and civilization have rules".this is true of humans within society as well.
