Final answer:
The Iroquois League made decisions through a consensus model, where representatives from each nation would reach a collective decision.
Step-by-step explanation:
The Iroquois League, also referred to as the Haudenosaunee or Five Nations, reached decisions through a process of consensus. In this process, representatives from each nation came together to discuss matters at hand and reach a collective decision. So, the most accurate option is: 'a. Representatives from each nation reached a consensus.'
This decision-making process emphasized unity and equality among the participating nations. The representatives were often the clan leaders or sachems of their respective tribes. The consensus model ensured that all nations within the Iroquois League had a say in the decisions that would affect them. This process is a notable aspect of the history of the Iroquois League.
