The statement that is NOT a reason that the Iroquois joined forces with the British is:
They wanted to join forces with the Algonquins and Hurons who were also fighting with the British.
The Iroquois allied with the British primarily due to their existing trade relationships, competition with other tribes, and the desire to counter French influence, rather than wanting to join forces with the Algonquins and Hurons, who were allied with the French.
