The correct answer is C) Irie.
The word that means peace and calm in the Jamaican culture is "Irie."
When Jamaican people use the term "Irie," what they try to say is that "everything is all right," "no problem, we are good," or "it is all right, we are in peace."
So next time you visit Jamaica in your vacations and you greet someone saying "Hello, how are you doing?" It is probably that they are going to answer "Mi irie" and they could add "Gaw Ghwaan" that could be translated as "How are you?.
These words, or course, are part of Jamaican slang.
