Answer:
D: There could be more American colonial settlements in the west.
D is the right answer. From 1754 to 1763, France and Great Britain fought over who would control North America in the French and Indian War. France had to give up its claims to land east of the Mississippi River because Great Britain won the war. This gave the American colonies access to a lot of new land, and they could now move west without worrying about the French getting in the way.
A is wrong because the French and Indian War didn't change much about how the Spanish lived in Florida. France and Great Britain fought the war, and Spain did not directly take part.
The French and Indian War ended French settlements east of the Mississippi River. So, B is the wrong answer. The British took over all the French territories east of the Mississippi, including Quebec, and France had to stop trying to settle in these areas.
C is wrong because the French and Indian War did not cause native settlements to spread to the east. On the other hand, many Native American tribes lost a lot of land, resources, and people because of the war.
