B is the answer. You can use process of elimination.
A) Many tribes were indigenous to New York, including the Mannahatta, for which the island of Manhattan is named, among others, so this can’t be it.
C) Most tribes traded, not only with one another but with the European colonists who settled on the continent. Trading was a significant part of native society, so the Iroquois were not alone here. (And by the way, if they were the only tribe who traded, who would they have traded with? XD)
D) Native Americans were known for living off the land and using natural resources in every aspect of life, so the Iroquois were not alone. As a matter of fact, every human civilization in history has used and has relied on natural resources to create items necessary for life, even into today, where we use oil for car gasoline, cotton and other plants to make our clothes, etc.
The Iroquois Confederacy wielded a lot of power in the Native community. Tecumseh, a key figure in Iroquois history, originally campaigned to align the 6 nations, and it proved successful for the Iroquois for a good period of time during the 19th century.
Hope I was able to help out!
