B. Thomas Jefferson completing the Louisiana Purchase
I believe this is the correct answer, because there was a lot controversy over the Louisiana Purchase, as there was nothing in the constitution about buying or selling land.

Penn owned the land and sold it to settlers at low prices instead of granting it out expecting to get a profit but he never did. This cause the opening of the colony which let it tho decline in the number of servants.
