The answer is most likely B
i studied it last year
they sold land for low prices for people that are willing to farm
hope this helps
The land was free and perfect for farming, if settlers survived the journey to Oregon the land was all theirs. But not only did the US like it, Britain and Russia also liked it. So the US told people to move there ASAP so it would officially be claimed by America.
I think it might be A but I’m not sure.
