Answer:
Option B, is the right answer.
Explanation:
A land deal between the U.S and France, through which the U.S received around 827,000 square miles of land in return for $ 15 million, is known as the Louisiana Purchase.
This purchase took place in the year 1803.
The purchase of the Louisiana territory extended the U.S. supremacy across the Mississippi River and resulted in multiplying the size of the nation.
The importance of this purchase can be seen in the fact that this purchase gave the United States control of the river Mississippi and New Orleans, which the U.S. farmers used to ship their crops and earn.
