The correct answer is A)It did not allow them to settle on land west of the Appalachian Mountains.
The British government forbid colonists from settling west of the Appalachian Mountains due to the fear of possible warfare with Native American groups living in these areas. Considering that the French and Indian War resulted in a significant amount of debt for the British government, the last thing the British government wanted was another expensive war overseas in which they send troops to the American colonies.
