The correct answer is D. The Louisiana Purchase, which doubled the size of the United States, is an example of a drastic boundary change.

Explanation:

At the Louisiana Purchase, the United States purchased more than 828,000 square miles of land from France in 1803. The total value of the transaction was of 15 million dollars or 80 million francs.

The territory of French Louisiana is much larger than the state of Louisiana in the United States today. From south to north, the territories include the shores of the Mississippi River in Louisiana (including New Orleans), Arkansas, Oklahoma, the northern border of Texas, the northeast corner of New Mexico, Missouri, Kansas, east of the Colorado, Iowa, Nebraska, most of Wyoming (east of the Rockies), west of the Mississippi River, Minnesota, south Dakota, most of North Dakota, most of Montana (except the western end), and the Missouri River Basin (also known as the southern border) in the Canadian provinces of Manitoba, Saskatchewan, and Alberta. The land area involved in the purchase of land is 22.3% of today's land in the United States, which is roughly equivalent to the original land area of the United States at that time, thus doubling the territory of the United States at that time.
