请问各位：代词指代对象如何确定呢？

代词指代对象如何确定呢？

什么情况下是指代主句的主语或者宾语，什么情况下是从句的主语或者宾语呢

比如OG第33题
From the earliest days of the tribe, kinship determined the way in which the Ojibwa society organized its labor, provided access to its resources, and defined rights and obligations involved in the distribution and consumption of those resources.
(A)and defined rights and obligations involved in the distribution and consumption of those resources
(C)and defined rights and obligations as they were involved in its distribution and consumption

C中的its 为什么不能指代the Ojibwa society 呢？
