Answer:
The correct answer is B. A problem for Britain after the French and Indian War was keeping colonists from going farther west into Indian lands.
Step-by-step explanation:
At the end of the French and Indian War, the British obtained all the French territories in what is now Canada, specifically Quebec.
During the war, the French allied with the native tribes, who saw the British Empire as an overwhelming power of their traditions and territories. When the war was over, even many native tribes subsisted on their ancestral lands, so the British had to take care not to cause new conflicts with them, since although they had won, the natives had proved to be an difficult enemy to overcome.
Therefore, as a way to avoid conflicts, King George III enunciated the Royal Proclamation of 1763, in which British settlers were forbidden to settle west of the Appalachian Mountains, since beyond this mountain range they were considered lands of native property
