Final answer:
Oglethorpe's plan for Georgia failed due to the presence of native tribes with pre-existing claims on the land.
Step-by-step explanation:
Oglethorpe's plan for Georgia failed primarily because most of the good farmland belonged to the natives, Option A. The indigenous tribes, such as the Creek and Cherokee, already lived and cultivated the land in Georgia. Oglethorpe's plan to create a colony based on small farms for the working poor clashed with the reality that the land was already occupied. Additionally, Option B is incorrect because Oglethorpe's plan did receive approval from the king, and there were no records of settlers leaving Georgia to go to Carolina, making Option C incorrect as well. Option D is partially true since Georgia did face difficulties in finding profitable markets for its crops, but it was not the main reason for the failure of Oglethorpe's plan.
