Answer:
The correct answer is D. A good historical evidence when studying Manifest Destiny would be the Louisiana Purchase treaty.
Step-by-step explanation:
The Louisiana Purchase was a commercial transaction whereby Napoleon Bonaparte, then French First Consul, sold in 1803 529,911,680 acres of French possessions in North America to the United States at a price of about 3 cents per acre; a total price of 15 million dollars or 80 million French francs. With interest, Louisiana's territory cost $ 23,213,568.
The Louisiana Purchase was framed in the process of American expansionism that took place in the 1800s. This expansionist process had its ideological foundation in the Doctrine of Manifest Destiny, which advocated the expansion of the United States from the shores of the Atlantic to the Pacific Ocean.
