Answer:
d. Population transfer
Step-by-step explanation:
As the scenario stated the Native Americans were forcibly moved to reservations. This is an example of population transfer. It is when a big group of people are moved from one area to another. This is usually done forcibly or against the will of the affected population. What is also unfortunate about this is that the populations affected are usually sent to unfamiliar places where they may or may not adjust well to.
