An example of balanced reciprocity among Trobriand Islander's can be seen in a. the sharing of labor when preparing the family garden. b. the sharing of food with parents. c. trade within the Kula Ring. d. gift giving within the nuclear family

c. trade within the Kula Ring.

Explanation:

Kula refers to an institution in  Trobriand Islands economic transaction where one receives red-shell discs arm shell or necklace and then it must be handed over to one of his partners. His partner, in effect, exchanges with him an opposite asset. So nobody can hold an article for a long lime. All who do not share quickly are pitifully blamed. This rule demonstrates that one transaction is not terminating the relationship within Kula trade. Kula relationship between two men is a lifetime affair and a lasting one.
