I believe the answer is A.
The Dawes Act allowed the US government to split up tribal lands into individual plots to sell, and Native Americans that didn’t take a plot couldn’t become citizens. This act was to separate Native American cultures, taking them into white society by making them farmers and ranchers.
So this act specifically means to divide and sell tribal land, so the most likely answer is A.
B has nothing to do with land
C Not true, their land was sold to others including whites
D this is true, but much of it wasn’t, it was sold to others looking for land.
I hope this helps!
