When you think about it, the geography of a location has a very important effect on history. The way how geography can affect history for example is through battles. If there was an army which had good archers and they were on a hill, they would obviously want to position their troops there in order to gain a good vantage point over their enemies and rain arrows down on them. This is one example how a hill could decide where a battle was fought.
Now, I cant say im 100% confident this is the answer, but it isn't B even though a war happened. A isnt right either in my opinion, as even though they didnt like the boundary problems after the French and Indian war, they werent terribly riled up. To me, I'd say its unfair taxes, as no taxation without representation was a big thing then. Also Interference from royal governors wasnt the problem often, it was the no contact.
