The Iroquois were made up of several groups who spoke a common language. Option B is correct.

The Iroquois were a League or Confederacy of tribes in the Northeastern part of America. Originally they were made up of five tribes: the Cayuga, Onondaga, Mohawk, Seneca, and Oneida. Later, in the 1700s, the Tuscarora tribe joined.

These american indians had a type of representative government and their own elected officials called chiefs.

i think it was because of how protected egyptian civilization was was which allowed them to evolve without much outside influence.
