Answer:
They were willing to accept anyone into the Nation as long as that person abided by the Iroquois Constitution.
Step-by-step explanation:
The Iroquois Constitution is an oral narrative that presented the 'constitution' that will regulate the Iroquois people and the formation of the League of Six Nations. This document is also referred to as the "Great Law of Peace", and contains the 'constitution' of the people.
This constitution was framed by Dekanawidah, the Great Peacemaker, and his spokesman Hiawatha, and written on wampum belts. And one aspect of the constitution was the issue regarding outsiders. In relevance to this issue, the document stated:
"If any man or any nation outside the Five Nations shall obey the laws of the Great Peace and make known their disposition to the Lords of the Confederacy, they may trace the Roots to the Tree and if their minds are clean and they are obedient and promise to obey the wishes of the Confederate Courier. they shall be welcomed to take shelter beneath the Tree of the Long Leave".
These lines show how the Iroquois people were willing to welcome anyone as long as their constitution is followed and the person/ individuals abide by it.
Thus, the correct answer is the third option.
