Which of the following is the example of creation of a third culture?

a. Lakisha is African American and her husband Mike is white American. To avoid
unnecessary conflicts, Lakisha and Mike decided not to mention the history of
slavery or racial discrimination in the U.S.
b. Judy is Native American, and her boyfriend Tanner is white American. Judy often
shares the stories her grandmother told her about the Native American histories:
history of oppression and colonization. Tanner feels guilty that his ancestors
oppressed Judy's ancestors.
c. Sandra is from Jewish family. Since she was a child her family told her the history
of oppression against Jews in Europe and discrimination in the U.S. Sandra's
friend Lacy, who is white American, keeps telling her Sandra should not cling
onto the past but should move forward.
d. Rebecca is an American Indian woman who married Brad, a white American man
who is Protestant. Rebecca and Brad decided to participate in both Rebecca's
tribal ceremonies and Christian holidays to understand each other's beliefs. They
also invite each others friends and families and talk freely about each other's
beliefs, as well as the history of relationship between American Indians and
whites in the U.S.
