The Answer Is B. The disease was from their own country so they had built up an immunity to it. While the People that where their before them had not, so it affected them more, caused more to be sick, and everyone to be weak. So therefore the Colonists where able to over power the people of that land.
I am pretty sure that the following which was the main benefit to the spread of disease in the New World for the colonists is being revealed by the option : “Limited number of Natives available to fight back against the colonists”. I choose this one because that was the point which led Natives to show their weakness and captured by the colonists. Hoope it helps!
