The correct choice regarding the effect of the French and Indian War on the Native American tribes who fought in it is:
They suffered negative consequences because they lost both their land and their allies.
After the war, the British emerged victorious and gained control over French territories in North America. This shift in power often led to increased encroachment on Native American lands by British settlers and a breakdown of alliances that had previously existed with the French. Many tribes found themselves losing both territory and crucial alliances, resulting in significant negative consequences for their communities.
